Pyroelectric material and its manufacturing method, and made thereof High efficiency pyroelectric fiber

The invention relates to a pyroelectric material and a manufacturing method and application product thereof, in particular to a pyroelectric material having a high-efficiency pyroelectric effect and a manufacturing method thereof, and a high-efficiency pyroelectric fiber produced therefrom.

The pyroelectric effect refers to the phenomenon that the polarization intensity changes with temperature and exhibits charge release. The substance that can produce the pyroelectric effect is called pyroelectric material. The pyroelectric material belongs to a class of piezoelectric materials and has no symmetry. There are crystals with special polar orientations in the center. Although there are thousands of materials with pyroelectric effects, there are only a dozen of them widely used, such as glycine sulfate (TGS) crystals and their homomorphic crystals, strontium ruthenate (SBN). Crystals, lithium sulphate (LSH) and lithium niobate (LiTaO ₃ ) crystals, etc., other than tourmaline crystals, piezoelectric ceramics such as PZT, and polymer films such as PVF2 are also pyroelectric materials.

Among various pyroelectric materials, tourmaline is widely used as a health care product because of the following characteristics:

(1) Tourmaline can emit infrared electromagnetic waves at normal temperature, and its wavelength range is close to that of human body. Therefore, the thermal effect of infrared rays emitted by tourmaline can activate the activity of activating biological macromolecules, improving circulation and enhancing metabolism. .

(2) The tourmaline itself has a spontaneous permanent dipole and a surface electric field of a certain intensity, and its electric field strength can reach up to E=6.2×10 ⁶ V/m at 10 μm on the crystal surface, which can be used for water molecules existing in the surrounding air. A slight ionization is carried out while H ⁺ and OH ^- are continuously produced. Among them, H ⁺ gets electrons from the weak current between the tourmaline electrodes and is reduced to hydrogen (H ₂ ), and OH ^- combines with water molecules to form air negative ions. The relevant chemical reactions are as follows: H ₂ O → OH ^- +H ⁺ .........(1)

2H ⁺ +2e ^- → H ₂ ↑.........(2)

OH ^- + nH ₂ O → OH ^- + (H ₂ O) _n ... (3)

In this way, the tourmaline can continuously release negative ions, and the negative ions can be used to remove free radicals in the human body, make the body fluids weakly alkaline, and improve air quality.

(3) The weak current of tourmaline can cause the bioelectrical effect of the human body, and achieve the functions of promoting metabolism, regulating the nervous system, circulatory system, and regulating the balance of cell membrane and internal and external body fluids.

The tourmaline crystal structure belongs to the trigonal system. The crystal belongs to the C3v point group and has a unidirectional polar axis. All piezoelectric constants d ₃₁ , d ₃₂ and d ₃₃ are positive values, with piezoelectric and pyroelectric properties, but tourmaline. The primary pyroelectricity is undetectable, and the observed pyroelectricity is usually caused by the second pyroelectricity, that is, the pyroelectric effect of tourmaline is not due to the temperature dependence of the spontaneous polarization of tourmaline. Sex, but the piezoelectric effect caused by the strain caused by thermal expansion, so the spontaneous polarization value of tourmaline crystals at room temperature is much smaller than that of general pyroelectrics, about Ps=0.011 μ C/cm ² , only The saturation polarization of BaTiO ₃ at room temperature is 1/2400 of 26 μ C/cm ² . In addition, although the wavelength range of tourmaline emission covers the range of vibration frequencies generated by human bodies or living organisms, its excitation frequency of light waves is slightly different from that of human body infrared photon electromagnetic waves, and thus cannot produce high-efficiency resonance effects. The excitation and absorption efficiency of the infrared rays produced by it is still not satisfactory.

Accordingly, it is an object of the present invention to provide a pyroelectric material capable of enhancing a pyroelectric effect and resonating with a target.

Thus, the pyroelectric material of the present invention comprises a pyroelectric substrate. The pyroelectric substrate is obtained by applying a high voltage electric field polarization to a material having polarity and magnetic properties.

The effect of the method for producing a pyroelectric material of the present invention is as follows: by selecting a material having a polarity and magneticity and belonging to a pyroelectric crystal system, and the main vibration frequency can cover the main vibration frequency of the electromagnetic wave emitted by the application object as the pyrolysis The electric material base material is polarized by applying a high-voltage electric field, and the polarization of the pyroelectric material of the pyroelectric material can be further increased by an applied electric field, so that the vibration frequency of the pyroelectric material is easier to apply. The interaction with the target object forms a resonance effect, so that the charge yield of the pyroelectric material and the charge absorption efficiency of the target are significantly improved. Therefore, the present invention can produce a material having high-efficiency pyroelectric characteristics and is highly practical. value.

The surface can be parallel to the fiber axis, especially when applied to a polar polymer, because the group has an effective dipole moment μ >0.5 (such as nylon, polyester, polyacrylonitrile, PVC fiber, etc.), so it will be along parallel fibers. The axial surface accumulates electric charge, which has a multiplying effect on the charge yield rate, so that the human body can raise the receiving surface of the effective electric charge when worn, and can form a resonance effect with the vibration frequency of the applied object through the pyroelectric material. The surface charge density of the material is increased, and the absorption cross section of the material to generate a charge is greatly increased, so that the product made of the fiber is given a stable and efficient pyroelectric effect, and is suitable for development as high functionality.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1 and 2, a preferred embodiment of the pyroelectric material 10 of the present invention comprises a sheet of pyroelectric substrate 11 and at least one nanoparticle bonded to the pyroelectric substrate 11 at intervals. Gold particles 12, and at least one carbon nanotube 13.

The pyroelectric material 10 is selected from a pyroelectric substrate material having polarity and magnetic properties and a nanometer gold particle raw material and a carbon nanotube raw material. After being combined into a premix, it is moved into a parallel plate capacitor of a high frequency ultrasonic pulse oscillator, and then a high voltage electric field polarization is applied to the premix, and an ultrasonic oscillator is activated to uniformly disperse the aforementioned raw materials. Got it. The pyroelectric substrate 11 is mainly formed by refining a pyroelectric material belonging to a non-centrosymmetric crystal, and includes a first surface 111 and a second surface 112 which are opposite to each other. The crystal structure of the pyroelectric material is a material belonging to a triclinic, monoclinic, orthorhombic, trigonal, cubic or hexagonal system, for example, mica, agate, quartzite, and Hetian jade, Synthetic intoxication, natural jade, natural diamonds, Tourmaline, Brucite, Calcite, dolomite, Colemanite, nepheline, kaolinite (Kaolinite), Helestone (Halloysite), and the like. Further, the pyroelectric material is refined to form a pyroelectric substrate 11 having a maximum diameter-to-width dimension of 100 nm to 100 μm and a thickness of 1/5 to 1/100 of the maximum diameter. In addition, in order to make the pyroelectric material 10 have an optimal use effect, the vibration frequency can be selected to cover the main vibration frequency of the electromagnetic wave emitted by the application object, and the polar and magnetic properties are also belong to the pyroelectric crystal system. The material is used as a raw material of the pyroelectric substrate 11.

The nano gold particles 12 are adsorbed on the pyroelectric substrate 11 by electrostatic force. After being polarized, the positive end of the electric dipole formed by the nano-gold particles 12 is attracted to the pyroelectric base by the attraction of the electric dipole negative charge formed by the polarization of the pyroelectric substrate 11 On the material 11, at the time of manufacture, by controlling the amount ratio of the pyroelectric substrate 11 to the nano gold particles 12, and in conjunction with the dispersion effect produced by the ultrasonic oscillator, the adsorbed on the pyroelectric substrate 11 is allowed. The nano gold particles 12 are produced on the other nano gold particles 12 that are close to each other. The electrical repulsion makes it difficult for the nano gold particles 12 to agglomerate to achieve a relatively favorable state of natural dispersion, and forms a state in which the number of bonded nano gold particles 12 on each of the pyroelectric substrate 11 is relatively average. Further, the particle size of the nano gold particles 12 is preferably 2 to 6 nm.

The carbon nanotube 13 is bonded to the pyroelectric substrate 11 by electromagnetic force and the nano gold particles 12, respectively. The single-walled carbon nanotubes will exhibit polarization and generate electric dipole moment under high-voltage electric field. The carbon tube tip has local electric field enhancement effect due to one-dimensional geometry. Positive ions in plasma will be preferentially supplied to the tip, positive ion selectivity. Providing a mechanical stress that may reduce the lateral direction applied to the carbon tube. After the polarization produces an electric dipole moment, the carbon nanotubes are aligned along the direction of the electric field, and when the polarization direction is upward and downward, the pyroelectric substrate 11 The second surface 112 and the first surface 111 disposed in the upper and lower directions form a dipole moment to accumulate positive and negative charges, respectively, to form positive and negative electrodes, so that the carbon nanotubes 13 are erected on the substrate 11 with a dipole moment inducing force. The second surface 112 and the second surface 111. In addition, when the carbon nanotube 13 is polarized in a high voltage electric field, the energy state at the bottom of the conductive strip contacts the valence band to produce semiconductor-metal transitions (SMTs) and exhibits a complete metal characteristic.

When the carbon nanotube 13 is a single-walled carbon nanotube, the diameter/length of the carbon nanotube 13 is preferably 0.2 to 5 nm × 10 to 250 nm. When the carbon nanotube 13 is a multi-walled carbon nanotube, the size of the diameter x length is preferably 0.2 to 3 μm × 10 to 100 μm.

It should be added that the merging of the carbon nanotubes 13 is still low by the electrostatic attraction force, and the pyroelectric substrate 11 and the carbon nanotubes 13 are also magnetized under a high voltage electric field, and the magnetic substrate 11 is magnetized. Up to near saturation magnetization. According to calculations, nanotubes generally at room temperature (about 25 ℃) under magnetic susceptibility (magnetization in) about 0.1 μ B / atom, in which the magnetic susceptibility of magnetic force strength of the pyroelectric substrate 11 is formed still It is not enough, but it is known that when the carbon nanotubes are placed in an environment in contact with a magnetic material, the carbon nanotubes can become magnetic. The mechanism of this phenomenon depends on the electrons. The transfer of the electric spin, that is, from the magnetic material to the carbon nanotubes, therefore, when the carbon nanotubes 13 are added and erected into the pyroelectric substrate 11, The electrorotation carried in the electrons of the pyroelectric substrate 11 will be transferred to the carbon nanotubes 13, thereby generating a considerable traveling magnetic field, and the magnetization ratio of the nanomagnetic metal is about ordinary magnetic metal. 20 times, the nano magnetic particles have a single magnetic domain effect, which increases the coercive field, and the coercive force is significantly improved, so that the carbon nanotubes 13 have a stronger magnetic force, which is enough for the The carbon nanotubes 13 are firmly adsorbed on the pyroelectric substrate 11.

In Fig. 2 of the present invention, although a first surface 111 of the pyroelectric substrate 11 is bonded to one nano gold particle 12, and the second surface 112 is combined with a plurality of spaced apart carbon nanotubes 13 is a view showing a main structural form of the pyroelectric material 10, but the bonding position and arrangement pattern of the nano gold particles 12 and the carbon nanotubes 13 on each of the pyroelectric substrate 11 are not limited. In addition, the pyroelectric material 10 can be made into a pyroelectric material by controlling the ratio of the amount of the pyroelectric substrate 11 , the nano gold particles 12 and the carbon nanotubes 13 at the time of manufacture. The combination of one or several nano gold particles 12 and one or several carbon nanotubes 13 on the bulk substrate 11 still achieves the purpose of enhancing the pyroelectric effect.

For example, the pyroelectric material 10 may also include a plurality of nano gold particles 12 bonded to the first surface 111 and the second surface 112 of the pyroelectric substrate 11 by electrostatic force and electromagnetic force, respectively. With a plurality of carbon nanotubes 13. Since the size of the pyroelectric substrate 11 is relatively large, when the ratio of the number of the nano gold particles 12 and the carbon nanotubes 13 to the single piece pyroelectric substrate 11 is 2 or more, regardless of the Whether the carbon tube 13 is of a cap type, after being subjected to high-voltage electric field polarization treatment and dispersion and jitter caused by the ultrasonic oscillator, and the carbon nanotube 13 is generated by the polarization, the electric dipole moment will be In the direction of the electric field, when the polarization direction is upward and downward, a dipole moment is accumulated on the second surface 112 and the first surface 111 of the pyroelectric substrate 11 to form positive and negative charges to form a positive and negative electrode, so that the nanometer is made. The carbon tube 13 is erected on the second surface 112 and the first surface 111 of the pyroelectric substrate 11 with a dipole moment inducing force. The carbon nanotubes 13 may be electromagnetically coupled to the second surface 112 of the pyroelectric substrate 11 through one end of the negative electrode thereof, or may be electromagnetically coupled to the pyroelectric base through one end of the positive electrode. The first surface 111 of the material 11 forms a pyroelectric material 10 as shown in FIG. 3, that is, except that at least one carbon nanotube 13 is bonded to the second surface 112 of the pyroelectric substrate 11 It is also possible that at least one of the carbon nanotubes 13 is bonded to the first surface 111 by electromagnetic force, and this configuration can still achieve the characteristics of the pyroelectric material using the characteristics of the nano gold particles 12 and the carbon nanotubes 13. The effect of the pyroelectric effect of 10. The pattern presented in FIG. 3 is a case where the first surface 111 and the second surface 112 of the pyroelectric substrate 11 are combined with a plurality of carbon nanotubes 13.

It should be noted that the pyroelectric material 10 is mainly selected after the base material of the pyroelectric crystal system having polarity and magnetic properties is mixed with a nanometer gold particle raw material and a carbon nanotube raw material as a premix. And applying a high-voltage electric field polarization to the premix by high-voltage alternating current, and using an ultrasonic oscillator to generate dispersion and beating, thereby making the nano-gold particle 12 electrostatically and causing the nano-particle The carbon tube 13 can be stably adsorbed and bonded to the pyroelectric substrate 11 by electromagnetic force. The applied electric field strength is about 10 ⁶ V/m~10 ⁸ V/m. In actual operation, it is adjusted according to the current change of the ammeter. When the current (amperes) suddenly rises, it means that The strength of the breakdown material (i.e., the saturated polarization field of the pyroelectric substrate 11 has been exceeded) should be about 3 to 5%, i.e., about the saturation polarization of the pyroelectric substrate 11 Electric field value.

In application, a pyroelectric substrate 11 containing a vibration frequency matching the vibration frequency of the application target is selected as a raw material due to the vibration frequency of the application target. The application object is not limited, and may be human body, gasoline or diesel, or water, and the pyroelectric material 10 is added to a product selected from the group consisting of fibers, internal combustion engine materials, and materials that dissociate water.

For example, when the object of the application is a human body, since the infrared photon vibration frequency of the human body is about 3.125×10 ¹³ HZ and the wavelength is 9.6 μm , the wave number is 1042 cm ^-1 , and the wave number is selected to be 1042 cm ^- The agate or quartzite which can detect the absorption peak in the vicinity of ^{1 is} a raw material of the pyroelectric substrate 11 and can be polarized by a high voltage electric field to enhance the polarization of the dipole molecule of the vibration frequency, so that the heat is increased. The pyroelectric substrate 11 is more easily oscillated with the infrared electromagnetic waves emitted by the human body, thereby further enhancing the vibration energy and increasing the vibration amplitude, generating strong infrared active absorption, and continuously starting the pyroelectric effect to form the ion carrier flow. The surface of the pyroelectric substrate 11 is accumulating a high-density electric charge, and the pyroelectric material 10 is made into a pyroelectric material 10 by screening with a pyroelectric substrate 11 having a molecular vibration frequency matching the infrared electromagnetic wave emitted from the human body. When the pyroelectric material 10 is added to a raw material of a fabric product such as a garment or a bed which is in contact with a human body, the high-density electric charge accumulated on the surface of the substrate 11 of the pyroelectric material 10 is also easily transmitted through resonance. The effect is a large amount of absorption by the human body, resulting in an efficient pyroelectric effect, achieving the object of the present invention.

When the application object is non-human, it can also be increased by adding the pyroelectric material 10 to a product or material that acts on the application object, for example, when selecting the main vibration frequency to cover The pyroelectric material substrate 11 having the main frequency of the gasoline and diesel 2962~2853 cm ^-1 and the CH stretching vibration frequency of 1470 to 1340 cm ^-1 is made into the pyroelectric material 10, and the pyroelectric material 10 is added to the material of the internal combustion engine. The characteristics of the pyroelectric material 10 can be utilized to produce a fuel-saving and carbon-reducing effect. In addition, when the pyroelectric material substrate 10 whose main vibration frequency covers the main frequency of water 3756±20cm ^-1 , 3657±20cm ^-1 and 1595±20cm ^-1 is selected, the pyroelectric material 10 is prepared. When the electroluminescent material 10 is added to the material that dissociates the water, the characteristics of the pyroelectric material 10 can be utilized to increase the dissociation effect of the water.

It is to be noted that, in the present embodiment, although the pyroelectric substrate 11 is combined with the combined structure of the nano gold particles 12 and the carbon nanotubes 13 as an example to explain the pyroelectric material 10, the pyroelectric material is used. The type of 10 is not limited thereto, and the pyroelectric material 10 may also include only the pyroelectric substrate 11 obtained by high-voltage electric field polarization, or may be adsorbed by the pyroelectric substrate 11 a material formed by the gold nanoparticle 12 on the pyroelectric substrate 11 or The pyroelectric material 10 can also be made of a material formed by the pyroelectric substrate 11 and the carbon nanotube 13 adsorbed on the pyroelectric substrate 11 so as to be transparent to a high voltage electric field. The polarization of the pyroelectric substrate 11 is enhanced, thereby causing the pyroelectric material 10 to produce an efficient pyroelectric effect as a whole.

Referring to Figures 1 and 4, a preferred embodiment of the method of fabricating the pyroelectric material 10 is further described. The preferred embodiment comprises the following steps:

Step 201 is to provide a pyroelectric substrate material comprising a plurality of pyroelectric substrates 11 each having a pyroelectric system and having polarity and magnetic properties. The material type and size range of the pyroelectric substrate 11 which can be used as the raw material of the pyroelectric substrate are as described above, and will not be described herein. Preferably, the pyroelectric material is selected in accordance with an application target for the pyroelectric material 10, and the main vibration frequency thereof is selected to cover the main natural vibration frequency of the application target. Further, a material having a polarity and a magnetic property of the pyroelectric crystal system is used as a raw material of the pyroelectric substrate.

As mentioned above, the known pyroelectric materials belong to non-central symmetry crystals, so the spontaneous polarization direction must follow a single axial direction, and among the known 32 point group symmetry crystal structures, only 10 The polar group of points satisfies this definition. They are triclinic, monoclinic, orthorhombic, trigonal, cubic, and hexagonal, respectively, and the point group is 1, 2, and 3. 4, 6, m, mm2, 4mm, 3m and 6mm, if the crystal belongs to the ten kinds of point groups corresponding to the crystal system, it can become a pyroelectric material. Among them, the pyroelectric materials are mostly mineral materials of cerium oxide. For example, the chemical composition of agate is mainly SiO ₂ and contains trace elements such as iron, manganese, nickel, etc., and the dissociation surface is layered or parallel strip. It belongs to the hexagonal system. The chemical composition of quartzite is also mainly SiO ₂ , belonging to trigonal and monoclinic systems.

In order to ensure that the pyroelectric substrate 11 can be a pyroelectric material having spontaneous polarization, since the pyroelectric body must be a crystal having no center of symmetry, that is, each unit cell has a certain intrinsic dipole moment, First select a crystal with polarity. Preferably, the selected mineral material belonging to the pyroelectric crystal system is first selected, and in addition, in order for the carbon tube to be erected on the substrate by magnetic force, the substrate needs to be magnetic, so magnetic separation is required to select a match. The pyroelectric substrate material is required.

Taking agate as an example, the method of screening is described. The agate belongs to the hexagonal system, and contains a trace element such as iron, manganese, nickel or the like. The crystal form is cryptocrystalline, and the monomer form is plate-like and piece-shaped. The divergent pattern of the shape, the mineral aggregate is a crystallographic form of cryptocrystals. Therefore, after cleavage and refinement, the cleavage plane will be parallel to the direction of the strongest bond in the crystal structure, that is, usually The mesh with the most dense arrangement of atoms occurs and obeys the symmetry of the crystal, so that a plate-like or sheet-like structure is formed. After the agate mineral is cleaved and refined into pieces having a surface width of about 1 mm or less, it is sent to a super magnetic dry powder conveyor magnetic roller magnetic separator, and the magnetic field strength of the magnetic roller is set to 1.5 Tesla (tesla The symbol is expressed as T) roughing operation to screen out the agate mineral material with weak magnetic properties, and then re-fine the selected magnetic agate sheet into particles with a size of about 0.3-50 μm, and then the magnetic field strength is 800~ The lowest magnetic susceptibility of 1600 kA/m magnetic separation is larger than that of X = 3 × 10 ^-4 cm ³ /g. During the electrification process, due to the interaction of electric field force, gravity, centrifugal force and friction force on the ore particles, the combined force of these forces determines the direction of the ore particles. The finely divided screening particles are polarized by a high-voltage electric field of 10 ⁴ to 10 ⁵ V/m, and the dipole moments of the selected polar particles are regularly arranged by the addition of an electric field, so that the crystal surfaces of the particles are electrically represented. Then, the polar agate particles are selected by the electrostatic ore to obtain a mineral material which can be used as the pyroelectric substrate 11. Wherein, the above Tesla (T) is an international unit system derivation unit of magnetic flux density or magnetic induction, and 1T=1V. s. m ^-2 .

In addition to agate, another commonly used material is mica, taking biotite as an example. The average specific magnetic susceptibility is about 54×10 ^-4 cm ³ /g, which is also a weak magnetic mineral that meets the specifications.

After screening the raw materials of the pyroelectric substrate in accordance with the specifications, the hot release after screening and purification treatment can be further carried out by spraying, washing, dehydrating, vacuum drying (to be dried to a water content of 100 ppm or less). The electrical substrate material is used in the subsequent steps.

Step 202 is to mix the pyroelectric substrate material with a nano gold particle raw material and a carbon nanotube raw material to form a premix, and the nano gold particle raw material includes a plurality of nano gold particles 12, The carbon nanotube raw material includes a plurality of carbon nanotubes 13. The size range of the nano gold particles 12 and the carbon nanotubes 13 used herein is the same as that described above, and therefore, the carbon nanotubes 13 used in the present embodiment are also in the form of one end of the cap and the open end of the other end. .

Step 203 is to apply a high-voltage electric field polarization to the premix, and cause it to be dispersed and beaten by the ultrasonic oscillator to be evenly stirred, so that the nano-gold particles 12 and the nano-carbon tubes 13 are evenly distributed, and Electric field polarization A plurality of pyroelectric materials 10 can be produced by combining electrostatic force and electromagnetic force on the pyroelectric substrate 11 respectively. Wherein, the applied electric field is formed by high-voltage alternating current, and after polarization of the high-voltage electric field, the opposite sides of the sheet-like or plate-shaped pyroelectric substrate 11 are respectively formed into positive and negative electrodes, and the carbon nanometer is formed. The particles 12 are also polarized to generate a strong electric field. During the stirring process, under the action of the strong electric field and the dispersion and bounce caused by the ultrasonic oscillator, the nano gold particles 12 are adsorbed to these by electrostatic force. On the pyroelectric substrate 11.

As described above, when the carbon nanotubes 13 are added to the pyroelectric substrate 11 , since the carbon nanotubes 13 are in contact with the pyroelectric substrate 11 , Under the action of a high-voltage electric field and a magnetic field formed by high-voltage alternating current, the pyroelectric substrate 11 will also be magnetized to generate a strong magnetic force, thereby rotating the electric rotation carried in the electrons to the nanocarbons. In the tube 13, it is possible to generate a considerable magnetic field of migration, thereby making the carbon nanotubes 13 more magnetic, so that the carbon nanotubes 13 are firmly adsorbed on the pyroelectric substrate 11 And it is not easy to fall off during use.

Wherein, when the carbon nanotubes 13 are carbon tubes having a cap structure at one end, a positive electrode is formed at one end of the cap, and a negative electrode is formed at the open end of the capless cap, and the mixture is uniform except during the stirring process. In addition to the dispersion, the second surface 112 of the positive electrode is formed by the end of the negative electrode bonded to the pyroelectric substrate 11 by the electromagnetic force, or the end of the positive electrode is erected to the pyroelectric base. The material 11 forms a first surface 111 of the negative electrode. Among them, the carbon nanotubes 13 can be selected without a cap or a cap. The multi-wall or single-walled carbon nanotube 13 can also be used, and the electric field can be controlled by electromagnetic force after the high-voltage electric field is polarized, so that the carbon nanotube 13 is stably adsorbed in the erect state in the pyrolysis. On the electrical substrate 11.

It is worth mentioning that when the multi-walled carbon nanotube 13 is combined with the pyroelectric substrate 11, the pyroelectric material 10 having the multi-walled carbon nanotube 13 generally releases charge infiltration and acts. Up to the deeper part of the application object, and the action part of the pyroelectric material 10 combined with the single-walled carbon nanotube 13 is relatively superficial, so the application order can be selected according to the application requirements and the required energy intensity. Wall or multi-walled carbon nanotubes 13.

In addition, the high-voltage electric field intensity applied in step 203 is required to be as close as possible to the saturation electric field strength to achieve the highest remnant polarization (Pr), and the polarization time of the high-voltage electric field is preferably at least 20 minutes. . When the polarization is actually performed, the electric field needs to be gradually increased. At this time, the current measured on the premix will also rise slowly. When the current surges, it indicates that the breakdown has occurred. At this time, the electric field is required to be slightly lowered to maintain a state close to the saturation polarization, and the micro-falling electric field is continuously subjected to polarization treatment for 20 minutes.

In order to achieve the result of complete polarization of the raw material in the premix, it is preferred to control the temperature of the polarized environment to be 50 to 150 ° C, so that the polarization of the domain molecules in the premix raw material is easier. For the movement, the applied high-voltage polarization electric field is preferably 10 ⁶ V/m to 10 ⁸ V/m. The polarization treatment was continued for 20 minutes under the aforementioned temperature and electric field intensity ranges. Typically, the breakdown voltage is exponentially related to temperature and is proportional to the thickness of the pyroelectric substrate 11 being processed, but for thin materials, the breakdown voltage is proportional to the square root of the thickness of the material. In addition, when the pyroelectric substrate material is wet, it may cause a breakdown voltage, which may affect the breakdown voltage value due to the material thickness, temperature and moisture content of the treated material. To avoid the occurrence of breakdown, it is preferred. Before the polarization treatment, the coercive electric field and the saturated electric field of the material to be processed are found and confirmed to prevent the applied electric field from being too high and causing material damage.

In step 202, the mixing ratio of the pyroelectric substrate raw material, the nano gold particle raw material and the carbon nanotube raw material may also be adjusted according to the application requirement, usually according to the average size of the sheet or the particulate matter in each raw material. And converting the number of the pyroelectric substrate 11 , the nano gold particles 12 and the carbon nanotubes 13 contained in the unit weight of the raw materials, respectively, according to the specifications and properties of the pyroelectric material 10 set, and Under the conditions and performance conditions, the average amount of the nano gold particles 12 to be bonded on each of the pyroelectric substrate 11 and the number of the carbon nanotubes 13 are adjusted to add the aforementioned raw materials to the premix. The amount ratio, after the application of the electric field in step 203 and the dispersion and jump action caused by the ultrasonic oscillator to uniformly disperse, the above-mentioned raw materials are evenly distributed, so that the plurality of pyroelectrics finally obtained can be obtained. Most of the material 10 can conform to the set material specifications. Thereby, a pyroelectric material in which the first surface 111 of the pyroelectric substrate 11 is bonded to one nano gold particle 12 and the second surface 112 is combined with a carbon nanotube 13 can be produced. 10, as shown in FIG. 3, the first surface 111 of the pyroelectric substrate 11 is combined with a plurality of nano gold particles 12 and a plurality of carbon nanotubes 13 (may also be combined with only one nanocarbon) The tube 13), and its second surface 112, also incorporates a pyroelectric material 10 of a plurality of carbon nanotubes 13 (which may also incorporate only one carbon nanotube 13).

In addition, in step 202, the pyroelectric base can also be made. The raw material is mixed with only the nano gold particle raw material, or the pyroelectric substrate raw material may be mixed with only the carbon nanotube raw material, and then the phase is mixed in step 203. The electric material base material and the nano-gold particle raw material, or the pyroelectric substrate raw material and the carbon nanotube raw material are applied with the high-voltage electric field polarization, and the dispersion and the bounce caused by the ultrasonic oscillator are used. The function is to disperse evenly, and a material having an efficient pyroelectric effect can be obtained. Alternatively, step 202 may not be performed, and in step 203, high voltage electric field polarization is directly applied to the pyroelectric substrate material of step 201. It is also possible to produce a material having an efficient pyroelectric effect.

The pyroelectric material 10 produced by the manufacturing method is prepared by using a pyroelectric substrate raw material having an oscillation frequency range close to the oscillation frequency of the application target as a main raw material, and then applying a high voltage electric field polarization treatment. The polarization of the pyroelectric substrate material can be enhanced, and the pyroelectric material 10 can be more easily oscillated with the infrared electromagnetic wave emitted by the application object to form a resonance to enhance the vibration energy, and the vibration amplitude is increased. Large, and the polarization of the dipole moment of the pyroelectric substrate 11 is further enhanced to generate strong infrared active absorption, and the charge accumulated on the surface of the pyroelectric substrate 11 is continuously released. The object of the application also has a strong absorption cross section for the electric charge emitted from the pyroelectric material 10 due to the principle of resonance absorption, wherein the field emission effect formed by the carbon nanotube 13 of the material 10 is Helping the charge accumulated on the surface of the pyroelectric substrate 11 to be more easily and concentratedly released, and reducing the charge being emitted into the environment before being applied to the application object, It can significantly improve the absorption efficiency of electrons or negative ions of the object (for example, the human body) of the application.

As described above, the application object in the step 201 may be a human body, gasoline, diesel or water, and the step 203 can be made by selecting the pyroelectric substrate 11 whose main vibration frequency covers the main frequency of the application target. The pyroelectric material 10 produced can be added to a product selected from the group consisting of fibers, internal combustion engine materials, and materials that dissociate water. Thereby, the effect of the aforementioned product or material can be enhanced.

It is worth mentioning that when the high voltage electric field is polarized in step 203, as the electric field increases, the energy gap in the carbon nanotube 13 transition from the bound state to the free state will be reduced, regardless of the single When the carbon atoms in the wall or multi-walled carbon nanotubes 13 are polarized by electromagnetic waves, they will cause the electrons in the outermost layer to transition to higher energy levels (π→π* transitions), and the effective work function can be greatly reduced ( Effective work function). When the applied electric field is increased to a certain value, the energy gap is greatly reduced, and even the energy gap is lost, so that the electronic properties can be adjusted by the strength and direction of the applied electric field, and the carbon nanotube 13 can be further transformed from the semiconductor. Metallization, forming semiconductor-metal transitions (SMTs). As the electric field strength increases, more SMTs are generated, and the electrons are more likely to escape at a low electric field strength, thereby allowing electrons to be easily emitted from the pyroelectric material 10 and increasing electrons. The kinetic energy makes it easier for the released electrons to penetrate deep into the object. Therefore, the electrons released from the pyroelectric material 10 thus produced can be efficiently absorbed by the applied object. For example, when the target is a human body, entering the human body to form negative ions can eliminate free radicals in the body and achieve health care effects. Among them, when the carbon nanotube 13 having a cap structure is selected, the cap structure at the end thereof makes the carbon nanotube 13 easier to form SMTs.

Through the action of the nano gold particles 12 bonded to the pyroelectric substrate 11, more carrier streams can be excited in the pyroelectric substrate 11 to increase the surface charge density of the substrate and form a more The remarkable spontaneous polarization effect is performed together with the carbon nanotubes 13 bonded to the pyroelectric substrate 11 to perform field-electron emission for the purpose of efficient pyrolysis.

However, the pyroelectric material 10 is formed of a simple pyroelectric substrate 11 only by mixing the pyroelectric substrate 11 with the nano gold particles 12, or only by the pyroelectric material. The substrate is formed by mixing with the carbon nanotubes 13, and a significantly enhanced pyroelectricity can be produced by the above-described treatment procedure of applying a high-voltage electric field saturation polarization, thereby developing various kinds of high-efficiency pyroelectric effects. A product with practical effects in application.

Referring to FIG. 5 and FIG. 6, a preferred embodiment of the high-efficiency pyroelectric fiber 100 of the present invention utilizes the aforementioned pyroelectric material 10 or the pyroelectric material 10 and a polymer base prepared by the foregoing method. The material 30 is mixed into a composite raw material, which is then melted and drawn. Wherein, the type of the polymer base material 30 is not limited, and for better effect, a polar polymer may be selected, and the group has an effective dipole moment μ > 0.5 (for example, nylon, polyester, polyacrylonitrile, PVC fiber, etc.). The high-efficiency pyroelectric fiber 100 can be further made into a fabric product such as clothing, bed sheets, and duvet covers. In addition, the amount of the pyroelectric material 10 is preferably 1 to 3 wt% of the total amount of the composite material, but the amount of the pyroelectric material 10 is not limited, and the pyroelectric material 10 can be adjusted according to the functional specifications required for the product. Add the ratio.

Wherein, in order to make the pyroelectric material 10 in the fabric product made of the fiber 100 bonded to the polymer polymer substrate 30 in a direction in which the object is easily applied to the object to provide a more remarkable use effect, The pyroelectric substrate 11 of the pyroelectric material 10 is prevented from being disposed and bonded to the polymer substrate 30 in such a manner that the first surface 111 and the second surface 112 are perpendicular to the axis direction L of the fiber 100. In order to adjust the arrangement direction of the pyroelectric materials 10, the pyroelectric materials 10 are uniformly added to the molten polymer substrate 30 to form the composite material, and the composite material is also A spinning hole 41 is emitted in the wire axis direction L before being cooled or set or solidified, and a polarizing device 42 capable of generating a DC high-voltage electric field is disposed along the wire axis direction L, and the arrangement orientation of the device 42 is adjusted so that It is capable of generating an electric field in a direction X perpendicular to the direction L of the wire axis, so that the pyroelectric material 10 that has not been shaped from the nozzle hole 41 is subjected to an electric field perpendicular to the direction L of the wire axis, and Making the dipoles in the pyroelectric materials 10 and The polar dipole moment of the polar polymer group is oriented in the direction of the electric field. That is, when the dipole moment molecules of the pyroelectric substrate 11 of the pyroelectric material 10 and the effective dipole moment of the polar polymer group are oriented along the electric field, the axis of the fiber is perpendicular to the 100 axis. The directions are arranged and frozen, so that the surface of the pyroelectric substrate 11 perpendicular to the dipole direction and the surface of the fiber having the polar group of the polar group in the direction of the effective dipole moment are respectively accumulated positive and negative charges. When the woven fabric 100 is worn, it is possible to prevent the accumulated electric charge from being efficiently released toward the body at an angle to the body surface, so that the fiber 100 becomes a highly efficient pyroelectric fiber. The electric field applied here is formed by direct current, and its electric field intensity is preferably from 10 ⁶ V/m to 10 ⁹ V/m.

<Specific example 1>

A mineral material mixed with agate and quartzite is refined and refined into pieces having an average diameter of about 10 μm as a raw material of a pyroelectric substrate, and the mineral material is estimated by the average weight of each pyroelectric substrate. The number of the pyroelectric substrate is further mixed into a specific amount of the above three raw materials by an average of one pyroelectric substrate corresponding to 10 nanometer gold particles and 10 carbon nanotubes. The premix is then subjected to an alternating current high voltage electric field of 10 ⁸ V/m to the mixed premix for 20 minutes for polarization, and then ultrasonically oscillated the premix after polarization by the high voltage electric field. By dispersing and beating, the premix can be mixed evenly. In addition, the ultrasonic device used in this embodiment uses a high-frequency pulse oscillator to generate a high-frequency voltage pulse and then replaces it into a mechanical vibration, and the crystal foil piezoelectric material uses lead zirconate titanate (PZT) for dispersion. The beating can achieve the best material mixing effect, and the ultrasonic design frequency is f=0.5×10 ⁹ /s~20×10 ⁹ /s (ie 0.5GHz~20GHz).

The appearance of the pyroelectric material A was compared with the pyroelectric effect, and the Fourier transform infrared spectrum (Fourier Transform Infrared Spectroscop, FTIR for short) of the pyroelectric substrate of the mixed agate and quartzite. The measurement of the light transmission spectrum, and the spectral measurement result of the pyroelectric substrate raw material is compared with the spectrum of a new strong black tourmaline material, and the results are as follows:

(1) Appearance: The appearance of the pyroelectric material A was observed using a transmission electron microscope (TEM), and the obtained image is shown in Fig. 7, showing the carbon nanotubes in the material A. 13 is indeed bonded to the surface of the pyroelectric substrate 11 in an upright manner on.

(2) Pyroelectric effect: The pyroelectric material A belongs to a pyroelectric material, and the spontaneous polarization of the pyroelectric material subjected to saturation polarization treatment by an artificial high voltage electric field is about 1.0 μC/cm ² or more, and the tourmaline is known. The spontaneous polarization is usually 0.011 μC/cm ² , and it is apparent that the pyroelectric material A of the present invention has a more pronounced pyroelectric effect than tourmaline.

(3) Main light transmission spectrum wavelength: It is known that the chemical composition of quartzite is the same as that of agate, both of which are cerium oxide minerals, but the crystal structure is slightly different, and the quartz mineral contains quartz as the main mineral. In addition, minerals such as mica and components such as hematite and goethite may be contained, and the absorption peaks of the FTIR spectra of the two may be slightly different. In the FTIR spectrum of quartzite, the infrared absorption spectrum band representing the stretching frequency of Si-O bond mainly appears at 1000cm ^-1 ~ 1350cm ^-1 , and the pyroelectric substrate raw material of mixed agate and quartzite in this specific example The FTIR spectrum measurement was carried out, and the results are shown in Fig. 8. It is shown that the main absorption peak position of the pyroelectric substrate material in which two kinds of mineral materials are mixed is at a wave number of 1043.451 cm ^-1 , and the permeation at the position is obtained. The rate is about 0.57, indicating that the light energy having a wave number of 1043.451 cm ^-1 is absorbed by 0.43 (43%) when passing through the pyroelectric substrate, and the wave value is converted into a wavelength of about 9.6 μm, and the known organism ( Containing the human body) The emission wavelength is approximately 9.6 μm. Therefore, when the pyroelectric substrate material is further made into a product which may be in contact with the human body, it should form a resonance effect with the infrared electromagnetic wave emitted by the human body, and then cooperate with a high voltage electric field polarization treatment to reach the highest residual pole. The strength (Pr) can improve the material charge output and the better charge absorption efficiency, and can achieve better use.

In addition, as shown in FIG. 9 , which is an emission spectrum of the wavelength-emissivity of the existing black tourmaline produced in Xinjiang, the existing tourmaline emission spectrum has a wavelength range of 2 to 20 μm, although the range covers the human body emission wavelength of 9.6 μm, but As shown in Fig. 9, the vibration peak is at 4.3 μm, and at 9.6 μm which belongs to the emission wavelength of the human body, it is the weakest point of its emissivity and intensity, so the vibration frequency of the dipole molecule and the infrared electromagnetic wave emitted by the human body are not Matching, no vibration coupling occurs to form a resonance effect to increase its vibrational energy, resulting in a lower piezoelectric effect, a relatively small absorption of infrared activity, and a small ion carrier flow and a low pyroelectric effect. It shows that when tourmaline is applied to human body, although it can provide a health effect by the action of negative ions generated by tourmaline, the negative ion excitation and absorption efficiency produced by it is not ideal.

<Specific example 2>

The pyroelectric material A obtained by the method of <Specific Example 1> and the polyethylene terephthalate (PET) masterbatch are mixed as a composite raw material, and the mixing ratio is 98.7 parts by weight. The PET masterbatch is added with 1.3 parts by weight of pyroelectric material A (ie, the amount of pyroelectric material A added to the composite raw material is 1.3 wt%), which is melted and drawn into fibers according to the existing spinning process, and then The produced fiber was woven into a cloth material, and a cloth piece having a size of about 3 cm × 5 cm was cut out as a test sample a. Observe the appearance of the fiber produced by microscopic observation, and send the sample a made of the fiber to the National Textile Products Quality Supervision and Inspection Center of the People's Republic of China for the test of the negative ion production concentration after 50 times of washing and the test. method The standard is CTTC F024-2007.

Please refer to Appendix 1 for the inspection report issued by the Testing Center of China Textile Science Research Institute. The results show that the negative ion concentration released by sample a before washing is 6050/cm ³ , and it is released after washing 50 times. The negative ion concentration is 5330/cm ³ . In addition, the negative ion concentration measurement of the Xinjiang tourmaline material shows that the negative ion concentration is at most 1000/cm ³ , and it is obvious that the composite material of the present invention is processed through a spinning process. Still retaining the ability to generate negative ions, and the resulting negative ionic product produced by the woven fabric product is still much higher than the negative ion generating amount of the simple tourmaline material, and thus is produced by the pyroelectric material A of the present invention. The fact that the negative ion release concentration of the product has been higher than the negative ion release concentration of the tourmaline material can also demonstrate that the pyroelectric material of the present invention will produce a higher concentration and a greater amount of negative ions than the tourmaline, indeed having The extremely efficient pyroelectric effect and practical value have better health effects in application.

In addition, after the sample a is washed 50 times, the release amount of the negative ions is maintained at 88% or more, and is far higher than the result of the negative ion production amount of the tourmaline material, the pyroelectric material of the present invention is not only the thermoelectric material of the present invention. It can be firmly combined with high molecular polymer, and it still retains the ability to stably release negative ions after processing, so it has practicality and durability as a functional product.

Further, as shown in FIG. 11, the fiber drawn from the composite material of the pyroelectric material A and PET in <Specific Example 1> is in an appearance state under an electron microscope, and the fiber surface protrusion is pyroelectric. The edge portion of the material A, that is, the main body of the pyroelectric material A, has been infiltrated into the inside of the fiber, and The fiber structure is closely combined with the PET material. Therefore, when the fiber is further woven into the cloth material, the sample A is not easily peeled off from the fiber even after repeated washing, and the pyroelectric material of the present invention is shown in combination with the above water washing test result. It can be firmly combined in the fiber, and it is not easy to fall off after being washed with multiple times. Therefore, the pyroelectric fiber and the cloth material can always maintain a stable release of negative ions, and it has practicality and durability for application to functional products.

<Specific example 3>

The pyroelectric material A prepared by the method described in <Specific Example 1> was prepared into test solutions a1, a2 and a3 at a concentration of 50 μg/ml, 100 μg/ml and 200 μg/ml, respectively, and the alumina was taken ( That is, a nanocapsule which can inhibit free radicals was prepared as a test solution having a concentration of 50 μg/ml and 100 μg/ml as a control. The test solution was separately cultured with mouse mononuclear macrophage RAW264.7 induced by 0.01 μg/ml of lipopolysaccharide (LPS) for 24 hours, and then determined by western blot. The expression of inducible nitric oxide synthase (iNOS) and β-actin (expression). In order to discriminate the effect of LPS, a blank test group 1 in which only macrophages were induced without LPS, and a blank test group 2 in which LPS-induced macrophages were not added to the test solution were set, and the same culture as in the test group was performed. The culture was carried out under the environment and conditions, and the expression of iNOS and β-actin protein was also determined by Western blotting method. The results of the above-mentioned assay regarding the expression amount of iNOS protein were plotted as a bar graph, and the results are shown in FIG.

Among them, iNOS is a protein related to inflammatory reaction, so it can be The inflammatory condition is judged by the amount of expression of iNOS. iNOS mainly contains inflammatory cells. When these cells are stimulated by bacterial toxins or inflammatory cytokines, they will secrete a large amount of nitric oxide to perform bactericidal or other immune regulation functions by strong oxidative power. Nitric oxide performs various functions in the human body. At the same time, due to its powerful antioxidant function, it becomes a strong free radical. Therefore, the use of inhibiting the production of nitric oxide (NO) free radicals is one of the main methods for evaluating anti-inflammatory activity. Although it can also be inhibited by drug steroids, it can cause many complications such as systemic swelling.

As shown in Fig. 10, lane 1 (lane 1) is a cell in a normal state and has not been given an LPS-induced inflammatory response, and its inflammatory protein iNOS has no significant expression, and lane 2 (lane 2) is the same cell administered with LPS to induce an inflammatory reaction. As a result, a large amount of iNOS expression was found, indicating that it was an onset group, and the iNOS expression amount of Dao 2 was used as a benchmark of 100%, and a growth bar graph was drawn. The results of lane 3~lane5 show that the higher the concentration of pyroelectric material A, the better the inhibition effect on iNOS, and when the concentration of pyroelectric material A is 100 μg/ml, There is a statistical difference, and at a higher concentration of 200 μg/ml, the expression of iNOS is only 61.39%, which is obvious compared to the control group of lane 6 (lane 6) and lane 7 (lane 7). It is seen that the pyroelectric material A does effectively inhibit the production of the inflammatory protein iNOS, thereby providing an effect of soothing the inflammatory reaction, thereby indicating that only the thermoelectric material A of only 20,000 parts (ie, 0.02%) can be added. Inhibition of about 40% of the inflammatory reaction, and the higher the concentration of the pyroelectric material A, the more obvious the inhibition of the expression of iNOS, the effect of the pyroelectric material of the present invention is indeed inhibited. . In addition, with the negative ion concentration of <Specific Example 2> As a result of the degree test, it can also be said that the pyroelectric material of the present invention can effectively suppress the inflammatory reaction, and should be related to its ability to release a high concentration of negative ions. As mentioned above, radicals are known to be substances that lack paired electrons. Therefore, when a user wears a garment to which the pyroelectric material of the present invention is added, the interaction between the body and the pyroelectric material on the garment is The high-efficiency pyroelectric effect formed can provide a large amount of electrons to the user's body at all times to eliminate free radicals and achieve an anti-inflammatory effect.

The pyroelectric material B is a pyroelectric material A only differs in that no nano gold particles are added at the time of manufacture, that is, a pyroelectric substrate raw material and a carbon nanotube (nano carbon tube addition ratio and pyroelectric material) A is the same. After mixing, it is prepared by applying a high-voltage electric field and ultrasonic waves to uniformly disperse. The pyroelectric material C is an unadded carbon nanotube, that is, a pyroelectric substrate material and a nano gold particle (the ratio of the nano gold particles are the same as the pyroelectric material A), and then a high voltage electric field is applied. The sound wave is oscillated and made. The pyroelectric material D is not added with a carbon nanotube or a nano gold particle, and is obtained by directly applying a high-voltage electric field to a pyroelectric wave by a pyroelectric substrate material, and the above materials A, B, and C, D was separately made into fibers according to the method described in <Specific Example 2>, and further woven into cloth materials a', b', c', d' containing materials A, B, C, D, respectively, and 3 g of each was cut. The cloth materials a', b', c', d' are used as test samples a", b", c", d", according to "GB/T 20944.3: Evaluation of antibacterial properties of textiles - Part 3: Oscillation method" In the manner described, the antibacterial performance evaluation of textiles was carried out. The strain used for testing was Candida albicans (storage number ATCC 1023), and the same material cloth with no added materials A, B, C, D was additionally cut. As a control sample, the test results are shown in Table-1 below:

The results of Table-1 show that the fabrics a', b', c', and d' woven by the fibers to which the pyroelectric materials A, B, C, and D of the present invention are added have an antibacterial effect, and even if not added Nano gold particles and carbon nanotubes, only for pyrolysis The pyrolysis material obtained by applying a high-voltage electric field polarization to the electric substrate can still provide an antibacterial rate of more than 86%, and the excellent antibacterial activity of the materials should also have an efficient pyrolysis with the pyroelectric material of the present invention. The electrical effect can provide a large amount of electrons. Therefore, the pyroelectric material of the present invention does have a high pyroelectric effect and can be applied to a bacteriostatic product.

It is worth mentioning that in order to verify the functional properties of the fabric material of the present invention in combination with the pyroelectric material, the cloth a' containing the pyroelectric material A is further made into a female underwear, and a clinical test is carried out, and the test results are confirmed. In the subject wearing the underpants containing the pyroelectric material A of the present invention, the menstrual symptoms were significantly improved, and it is apparent that the pyroelectric material of the present invention does have practical functions. The results of the aforementioned clinical trials have been included in the Clinical Trials database, experiment number NCT01449305.
