It has a cross-sectional area of several hundred nanometers. This process can control the thickness of the fiber by varying the size of the electric field and the concentration of the polymer solution.

A number of methods for producing nanofibers using electrospinning have been proposed. For example, Korean Registered Patent Publication No. 10-1766143 (Registration Date: 2017.08.01) relates to a method for manufacturing aligned activated carbon nanofibers using an electrospinning method, and in one direction when a rotating current collector is operated at a high speed. Alignment can provide an excellent path for increasing the ion transport rate, thereby making it possible to manufacture activated carbon nanofibers with improved electrical properties.

On the other hand, in a place where many people are gathered, in the kitchen of a restaurant, and in industrial sites that use oil or processed oil, a large number of oil particles are present in the air, and particles with these oils cause various diseases to humans and improve filter performance. Weaken.

In order to prevent this, a filter having oil resistance is manufactured and used, but this is a situation in which the ability to collect bacteria and viruses is much lower than that of a conventional filter.

Also, it should not be construed as being limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows a state of manufacturing an oil resistance antibacterial filter using electrospinning according to the present invention.

In the case of the existing filter, only the properties of oil resistance or antibacterial function is provided, but the oil resistance antibacterial filter (hereinafter referred to as a filter) 1 according to the present invention is produced by spinning fibers 10 having oil resistance properties The filter 1 coated with the antibacterial substance 50 is manufactured by spraying the filter 1 with the antibacterial substance 50 on the filter 1.

The filter (1) according to the present invention discharges at least two kinds of polymer materials (12) (14) to produce fibers (10) of the electrospinning portion (20) and the fibers (10) produced by the electrospinning portion (20). ) Is composed of a coating part 40 that provides an antibacterial material 50 toward the laminated substrate 30 by discharging the substrate 30 and the fibers 10.

The electrospinning section 20 is to produce fibers 10 by discharging polymer materials 12 and 14 made of at least two types, and dispensing fibers 10 by mixing polymer materials 12 and 14. . In addition, the first polymer material 12 is disposed inside, and the second polymer material 14 is disposed outside to produce fibers 10 having a concentric cross-section.

The fibers 10 discharged from the electrospinning section 20 have oil resistance properties on at least one polymer material 12 and 14, and thus have oil resistance properties on the produced fibers 10 themselves. In addition, if the fibers 10 to be discharged are densely and uniformly arranged, the filter 1 of a material having high resistance from oil may be manufactured.

The substrate 30 is positioned to be spaced a predetermined distance from the nozzle of the electrospinning portion 20, thereby collecting the fibers 10 to form a filter 1. The surface of the fiber 10 can be easily coated with the antibacterial material 50 by spraying the antibacterial material 50 from the coating part 40 toward the filter 1 collected on the substrate 30, and the electrospinning part It may be used as a means for supporting the fiber 10 to dry or heat the fiber 10 freshly discharged from (20).

The coating part 40 sprays the antibacterial material 50 so that the fiber 10 discharged from the electrospinning part 20 has antibacterial performance against viruses or bacteria. ). At this time, the coating unit 40 may coat the surface of the fiber 10 in various ways according to a method or device for coating the fiber 10, and detailed description thereof will be described below.

Figure 2 shows a flow chart for the manufacturing process of the oil resistance antibacterial filter using electrospinning according to the present invention.

In the manufacturing process of the filter including the oil resistance property and the antibacterial function, a first polymer material including one of the PGS polymer and the PSF polymer is disposed on the inside, and a second one containing the other of the PGS polymer and the PSF polymer on the outside. The step of electrospinning (S10) in which a polymer material is disposed to form concentric circles on the cross-section, the step of coating an antimicrobial material on the surface of the structure formed by electrospinning (S30), and drying the structure coated with the antibacterial material ( S40) and heating the dried structure in an oven forming a vacuum atmosphere (S50).

Here, the first polymer material 12 is a PGS polymer solution of 50% (w/v), mixed with glycerol and sebacic acid in a 1 to 1 ratio, and stored in an argon atmosphere at 120 degrees for 24 hours. Then, a PGS polymer solution is prepared. Then, a solvent mixed with tetrahydrofuran (THF) and dimethylformamide (DMF) in a 1:1 ratio and a PGS polymer solution are mixed to prepare a 50% (w/v) PGS polymer solution. .

The second polymer material 14 is a PSF polymer solution that forms a concentration of 20% (w/v), tetrahydrofuran (THF) and dimethylformamide (DMF) in a polysulfone (PSF) polymer solution. Is mixed in a 1:1 ratio of solvent to prepare a 20% (w/v) PSF polymer solution.

Looking at the process of manufacturing the filter (1), the nozzle of the electrospinning unit 20 is coaxially arranged as many as the number of polymer materials in the step (S10) of electrospinning in the form of concentric circles when spinning the fiber (10) The first polymer material 12 is located at the center of the fiber 10, and the second polymer material 14 is wrapped around the outer circumferential surface of the first polymer material 12. At this time, at least one polymer material 12 or 14 of the first polymer material 12 or the second polymer material 14 has an oil resistance property, so that the fiber 10 will have resistance from oil particles.

The fibers 10 sprayed from the nozzle are seated on the substrate 30 to form the filter 1. In order to improve the filtration performance of the filter 1, the fibers 10 having a small thickness should be densely and uniformly arranged. something to do. In order to fabricate the filter 1 having excellent filtration performance, since the gap between the nozzle and the substrate 30 is important, it is better to install the substrate 30 so that the gap can be adjusted vertically from the nozzle. Preferably, it would be better to set the distance between the nozzle and the substrate 30 to 17 cm.

In the step (S30) of coating the antibacterial substance, the surface of the fiber 10 is sprayed with the antibacterial substance from the coating portion 40 while the fiber 10 discharged from the electrospinning portion 20 is seated on the substrate 30 Is coated with an antibacterial material (50). At this time, it is divided into electrospray, electro-aerodynamic, and spark discharge according to a method or apparatus for spraying the antibacterial substance 50 from the coating part 40.

The drying step (S40) is to dry at room temperature until the surface of the fiber 10 coated with the antimicrobial material 50 is sufficiently hardened, preferably drying the fiber 10 in air for at least 6 hours.

In the heating step (S50), the sufficiently dried fiber 10 is heated in an oven to remove foreign substances remaining on the surface of the fiber 10, or a substance having a lower melting point than the heating temperature disappears to form a number of pores. This will further improve the filtration performance. Preferably, the PGS polymer contained in the fiber 10 is cross-linked by heating in an oven forming a vacuum atmosphere of 130 degrees for 48 hours. PGS polymer cross-linking is a phenomenon in which covalent bonding occurs between a protein and a protein, between a protein and a nucleic acid, or between double strands of DNA, and is involved in the stabilization of a structure in intra-molecular transverse and intermolecular transverse coupling.

The fiber 10 after completing the above process may be used as a filter 1 including an antibacterial function while having resistance to oily particles.

On the other hand, in addition to the method of manufacturing the fiber 10 in the form of a concentric circle having the aforementioned cross-section, the oil required for the filter 1 is produced even if the fiber 10 is produced by mixing a polymer material having oil resistance and another polymer material. It can have resistance properties.

Figure 3 shows a flow chart for another manufacturing process of the oil resistance antibacterial filter using electrospinning according to the present invention.

The method of manufacturing the filter 1 by discharging the fibers 10 in which at least two polymer materials 12 and 14 are mixed without discharging them according to the type of the polymer material is as follows.

Preparing a mixture by mixing a first polymer material containing one of the PGS polymer and a PSF polymer and a second polymer material including the other of the PGS polymer and the PSF polymer (S12); Injecting and electrospinning (S20), coating the surface of the structure formed by electrospinning (S30), drying the structure coated with the antimicrobial material (S40), and drying the structure in a vacuum atmosphere It includes the step of heating in the oven to form (S50).

The step of preparing the mixture (S12) is to prepare the mixture 12 and 14 by mixing in one place without separating the first polymer material 12 and the second polymer material 14, and the first polymer material 12 And at least one polymer material of the second polymer material 14 should have oil resistance properties. Here, the first polymer material 12 and the second polymer material 14 use the above-mentioned 50% (w/v) PGS polymer solution and 20% (w/v) PSF polymer solution. It would be nice to do In addition, any polymer solution having oil resistance properties may be used.

In the step of electrospinning (S20), a mixture (12) (14) in which at least two polymer materials of different types are mixed is contained in one storage unit, connected to the electrospinning unit (20), and then the fibers (10) It is discharged to the substrate 30 to form the filter 1. The fiber 10 discharged from the nozzle of the electrospinning section 20 is a mixture of the first polymer material 12 and the second polymer material 14, and the cross section of the fiber 10 forms one layer. .

The following process will be omitted because the same process as the process of manufacturing the filter 1 with the concentric circle-shaped fiber 10 mentioned above is omitted.

Figure 4 relates to a first embodiment for coating an antibacterial substance in the oil resistance antibacterial filter using electrospinning according to the present invention.

A coating portion 40 is provided for coating the filter 1 by spraying the antibacterial substance 50 by electric spraying on one piece of the electric spinning portion 20 for discharging the fibers 10 or the fiber 10 after the electric spinning is finished. have.

The coating part 40 is a syringe 412 provided with a solution containing the antimicrobial material 50, and the surface of the fiber 10 by spraying the antimicrobial material 50 from the syringe 412 to one side of the structure The pump further includes a power supply unit 420 for supplying power to the pump 410 and the pump 410 to enable the coating of the antimicrobial material 50 to be electrosprayed.

The power supply unit 420 supplies power to the pump 410 to form an electric field, and the balance between the electrostatic force pulled by the electric field on the surface of the antibacterial material 50 and the surface tension of the antibacterial material 50 is broken, and is very fine. Formed spray particles are generated. When the spray particles adhere to the surface of the fiber 10 of the filter 1 and coat the filter 1, a filter 1 further comprising an antibacterial function is formed.

In the syringe 412, an antimicrobial material 50 capable of coating the fiber 10 with an antibacterial material 50 and a solution mixed with the antibacterial material 50 to facilitate spraying are mixed and stored together. The paper 412 is installed on the pump 410, the injection nozzle 413 provided on the pump 410 to filter the antibacterial substance 50 stored in the syringe 412 toward the fiber 10 is filtered It is located toward (1). In addition, the power supply unit 420 supplies power to the pump 410 so that the pump 410 is pumped so that the antibacterial material 50 of the syringe 412 can be injected into the fiber 10.

The pump 410 may be classified according to the polarity of the spray nozzle 413 spraying the antibacterial material 50. That is, the spray nozzle 413 spraying the cationic antibacterial material 50 and the spray nozzle 413 spraying the anionic antibacterial material 50 may be separately provided. As the antibacterial material 50 is sprayed according to the polarity, the adhesion or coating degree of the filter 1 and the antibacterial material 50 may be further improved.

5 is a second embodiment of coating an antimicrobial material in the oil resistance antibacterial filter using electrospinning according to the present invention.

By coating the antibacterial material 50 on the surface of the fiber 10 by generating sparks, a chamber 430 in which a space is formed so as to generate sparks, and installed inside the chamber 430, sparks In addition, a pair of electrodes 432 to which voltage is applied and an air supply unit 440 that supplies air to the interior of the chamber 430 body and injects it to one side of the structure are further included.

The chamber 430 is provided with a space therein to enable the generation of sparks, and an inlet and an outlet to enable communication between the inside and the outside of the chamber 430 are formed.

The electrode 432 is located inside the chamber 430 so that a pair is installed facing each other, and a high voltage that generates sparks is applied. Preferably, nickel (Ni), silver (Ag), platinum (Pt) is formed of a metal material having sterilization and antibacterial properties, a metal of carbon, or a metal material having adsorption properties such as titanium dioxide to discharge nanoparticles do. That is, when a high voltage such as a positive voltage or a negative voltage is applied to the pair of electrodes 432, the metal is vaporized by spark discharge to form particles.

On the other hand, the smaller the spacing between the electrodes 432, the lower the ignition induction voltage, and the larger the spacing, the higher the voltage required. This means that if the distance between the electrodes 432 is narrow, the required voltage for generating the arc is reduced, while the minimum ignition energy due to the short spark can be transmitted to generate misfire. Therefore, it is preferable that the electrodes 432 according to the present invention are arranged at intervals at which a predetermined amount of high voltage can be applied without misfire.

The air supply unit 440 is connected to the inlet of the chamber 430 to supply air to the space formed in the chamber 430, and various supply means may be used. For example, air containing an inert gas or nitrogen may be supplied by a flow meter such as a carrier air supply system (MFM) or a mass flow meter (FMM). In addition, after the air is compressed, the compressed air may be passed through the HEPA filter 442 to supply filtered air to the chamber 430.

The antibacterial material 50 formed in the chamber 430 is sprayed on the filter 1 through the air supply unit 440 to coat the fiber 10. However, before coating the fiber 10, the antimicrobial material 50 undergoes a series of processes through the soft X-ray generator 450 and the duct 460, and then the fiber 10 is coated. This could be done.

The soft X-ray generator 450 makes the polarity of the nanoparticles generated in the electrode 432 into a charge neutral state. That is, the polarity of the antimicrobial material 50 is made to be neutral so that the antimicrobial material 50 that has become nanoparticles can be charged with a specific polarity.

The neutral antibacterial material 50 is introduced into the duct 460, passes through the charge and filter 1 with a certain polarity such as the polarity of the positive electrode or the negative electrode, and then the antibacterial material 50 is discharged toward the filter 1 The fibers 10 are coated.

FIG. 6 relates to a third embodiment of coating an antimicrobial material in an oil resistance antibacterial filter using electrospinning according to the present invention.

The present embodiment is to coat the antimicrobial material 50 to the fiber 10 by using electro-aerodynamic, an air supply unit 440 for supplying compressed air toward the filter 1, and an air supply unit ( Compressed air supplied from the 440, the vaporization unit 480 for vaporizing the solution provided with the antimicrobial material 50 in the form of a gas, and a drying unit for removing moisture from the vaporized gas in the vaporization unit 480 ( 490) and a spray nozzle (413) provided to allow the coating of the antibacterial material (50) by spraying the filter (1) by charging the antibacterial material (50) of the gas from which the moisture is removed from the drying unit (490) to a predetermined polarity. ).

The air supply unit 440 generates compressed air, which is a carrier gas for transporting the antimicrobial material 50, and supplies it into the vaporization unit 480. The air supply unit 440 may be provided with a HEPA filter 442 for filtering fine particle impurities contained in compressed air and a regulator 444 for controlling pressure, flow rate, speed, etc. of compressed air. Will be able to.

The compressed air supply unit 440 is controlled by a mass flow controller (MFC) 470 so that compressed air can flow to the vaporization unit 480. The mass flow controller 470 is a device for measuring and controlling gas flow, and is specially designed according to the type of gas and the range of the flow velocity. Therefore, the mass flow controller 470 may control the flow of the antimicrobial material 50 by adjusting the set value from 0% to 100% in a predetermined range.

The vaporization unit 480 vaporizes the antibacterial substance 50 in a droplet state as a gas by spraying it in a mist form by applying a certain pressure to the antibacterial substance 50 solution in which the antibacterial substance 50 is dispersed. In addition, the antimicrobial material 50 vaporized in a droplet state flows into the interior of the drying unit 490 together with compressed air as a carrier gas. At this time, a flow meter capable of measuring the flow rate of the compressed air flowing into the vaporization unit 480 may be further installed on the compressed air movement passage prior to entering the vaporization unit 480.

The drying unit 490 removes moisture contained in the antibacterial material 50 vaporized in a droplet state through the vaporization unit 480. A diffusion dryer may be used as the type of the drying unit 490, droplets may be collected in the diffusion dryer, and a replaceable desiccant is incorporated.

The desiccant removes moisture in the antimicrobial material 50 that is moved along the flow of compressed air using a diffusion capture method. Since the desiccant can remove moisture without contacting the antibacterial material 50, loss of the antibacterial material 50 can be minimized.

The antimicrobial material 50 and the compressed air that have passed through the drying unit 490 pass through the soft X-ray generator 450 that maintains the particles in a charge neutral state. The soft X-ray generator 450 serves to make the antibacterial material 50 into a charge neutral state before the antibacterial material 50 enters the charging device.

The spraying nozzle 413 is coated by spraying the antimicrobial material 50 onto the filter 1, and the spraying nozzle 413 is further equipped with a charging device that converts the polarity of the antibacterial material 50. Therefore, when the antibacterial material 50 is charged and sprayed with a polarity opposite to that of the fiber 10, a larger amount of the antibacterial material 50 may be attached to the surface of the filter 1.

The present invention described above is not limited by the above-described embodiments and accompanying drawings, and various substitutions, modifications, and changes are possible within the scope of the present invention without departing from the technical spirit of the present invention. It will be apparent to those who have the knowledge of.
