1 illustrates a dust collecting filter 100 according to an embodiment.

Referring to FIG. 1, the dust collecting filter 100 may include a base 110 and a plurality of pores 120.

The base 110 may comprise a polymer material. Illustratively, the polymer material used for the base 110 may include at least one of silicone oil, a fluoropolymer, or a composite thereof.

Depending on the embodiment, the base 110 may be formed in the form of a film. For example, an adhesive portion (not shown) may be formed on at least a portion of the upper and lower surfaces of the base 110 so that the dust collecting filter 100 is attached to the skin attachment.

A plurality of pores 120 may be formed in at least one of the upper and lower surfaces of the base 110. For example, the pores 120 may be formed to be dispersed throughout the space of the base 110 and thus may be formed on both the upper and lower surfaces of the base 110.

The pores 120 may be formed in a size larger than that of fine dust to be adsorbed. The dust collecting filter 100 of this embodiment is a method of adsorbing fine dust by using electrostatic force using triboelectric, as will be described later, so even if the size of the pores 120 is larger than that of fine dust, the adsorption performance of fine dust is lowered. It doesn't work.

A flow path of air through the pores 120 may not be formed between the upper and lower surfaces of the base 110. A general dust collecting filter allows air to penetrate through pores, etc., and filters fine dust through pores of a size smaller than that of fine dust, but the dust collecting filter 100 of this embodiment allows air to penetrate through the dust collecting filter 100. Rather, when air flows in a direction substantially parallel to the upper or lower surface of the dust collecting filter 100, the air that penetrates between the upper and lower surfaces of the base 110 is a method of adsorbing fine dust by electrostatic force generated by friction. There is no need to form a passage, and due to this difference, even if fine dust is adsorbed, there is an advantage that it does not disturb the air flow.

FIG. 2 is a diagram illustrating a principle in which the dust collecting filter 100 adsorbs fine dust according to an exemplary embodiment.

1 and 2, the dust collecting filter 100 may be disposed to be substantially parallel to a direction in which air flows. For example, as shown in FIG. 2, when air containing fine dust 20 flows in a direction substantially parallel to the upper surface of the dust collection filter 100, the dust collection filter 100 is generated by the flow of air. Fine dust 20 may be adsorbed using triboelectric. It is different from a method in which a general dust collection filter is disposed perpendicular to the direction in which air flows and filters air when it passes through the dust collection filter.

Depending on the embodiment, the dust collecting filter 100 may be used in a state attached to the skin complex 10. In this case, it may be understood that the dust collecting filter 100 and the skin complex 10 together constitute a dust collecting device. Depending on the embodiment, all of the dust collection filter 100 is attached to the skin complex 10 and used, or a part of the dust collection filter 100 is attached to the skin complex 10 and a part of the dust collection filter 100 is attached to the skin complex 10 It can also be used without being attached to (10).

Although there is no particular limitation on the skin complex 10, it is preferable that it is an object that causes the flow of air or where there is a flow of air. For example, the skin complex 10 may be a vent of an air conditioner, a wing of an electric fan, a screen, or a filter having a large pore, but is not limited thereto.

The dust collecting filter 100 may be attached to the skin complex 10 in various ways. For example, an adhesive portion may be formed on all or at least a portion of an upper surface or a lower surface of the base 110. The adhesive portion may be formed of an adhesive or may be formed of an adhesive coating.

The dust collecting filter 100 of the present embodiment includes a base 110 formed of a polymer material including at least one of silicone oil, a fluoropolymer, or a composite thereof, so that air flows along one surface of the dust collecting filter 100 When doing so, it is possible to easily generate static electricity due to friction.

In addition, the plurality of pores 120 formed in the dust collecting filter 100 may increase the area in which the polymer material contacts air to further increase triboelectricity, thereby more effectively adsorbing fine dust.

As described above, the dust collecting filter 100 according to the present embodiment may be disposed where there is a flow of air to absorb fine dust using triboelectric electricity generated by the flow of air. At this time, the dust collection filter 100 does not allow air to pass through the dust collection filter 100, but when the air flows in a direction substantially parallel to the dust collection filter 100 (that is, when air flows through the dust collection filter 100). It is possible to effectively reduce fine dust without disturbing the flow of air by adsorbing fine dust using triboelectric electricity generated when it flows along one side.

3 and 4 each illustrate a dust collecting filter according to an embodiment.

Referring to FIG. 3, the dust collecting filter 300 is different from the dust collecting filter 100 illustrated in FIG. 1 in that it further includes fine metal particles 330.

The metal particles 330 may be micro- or nano-sized metal materials. For example, the metal may be gold (Au), but is not limited thereto. For example, at least some of the metal particles 330 may be attached to the pores 120. When the metal particles 330 having many free electrons rub with air, the triboelectricity of the dust collecting filter 300 increases, so that fine dust can be more efficiently adsorbed.

Referring to FIG. 4, the dust collection filter 400 may further include fine particles 440 compared to the dust collection filter 300 illustrated in FIG. 3.

According to an embodiment, the microparticles 440 may be formed to be spatially dispersed in the base 110.

For example, the microparticles 440 may be micro- or nano-sized dielectric materials. The dielectric material may include at least one of barium titanate, titanium dioxide, or lead zirconate titanate, but is not limited thereto.

For example, the microparticles 440 may be micro- or nano-sized polar materials. The polar material may include at least one of sucrose, sodium chloride, or xylitol, but is not limited thereto.

When the dust collection filter 400 further includes a dielectric material or a polar material, the amount of charge due to friction with air increases, so that the dust collection filter 400 may more efficiently adsorb fine dust.

5 illustrates a method of manufacturing a dust collecting filter according to an embodiment.

First, a base material may be formed by mixing a polymer material 510 with a dielectric material 520 having a micro or nano size and a polar material 530 (see FIG. 5(a)). For example, the polymer material 510 may include at least one of silicone oil (PDMS) or a fluoropolymer. For example, the dielectric material may _{include at least one of barium titanate (BaTiO 3} ), titanium dioxide, or lead zirconate titanate, and the size may be 100 nm or less. For example, the polar material may include at least one of sucrose, sodium chloride, or xylitol, and the size may be several μm or less.

Next, the base material may be cured to form the base 540 (see FIG. 5(b)). For example, a curing agent corresponding to 10:1 in weight ratio to the base material may be added to the base material and cured at 20°C to 100°C for 2 hours. Illustratively, the curing temperature is preferably 80°C. The cured base 540 may include a dielectric material 520 and a polar material 530.

Next, the cured base 540 may be immersed in the solution 550 to dissolve the polar material 530 (see FIG. 5(c)). For example, the cured base 540 may be immersed in water 550 at 20°C to 100°C for 2 hours or more. For example, it is preferable that the temperature of the water 550 is 100°C.

After passing through the dissolution process of the polar material 530, the dried base 560 may be a porous structure including a plurality of pores 590 by dissolving all or at least a part of the polar material 530 (FIG. 5 ( d) see).

Next, the porous base 560 may be impregnated in the solution 570 in which the metal nanoparticles 525 are dissolved (see FIG. 5(e)). For example, the metal nanoparticles 525 may include gold (Au). For example, the size of the metal nanoparticles 525 may be 100 nm or less. For example, the porous base 560 may be immersed in the solution 570 in which the metal nanoparticles 525 are dissolved for about 6 hours.

Next, the dust collecting filter 580 in which the metal nanoparticles 525 are dispersed in the porous structure 560 may be formed by drying the porous base 560 on which the impregnation process has been completed (see FIG. 5(f)). To this end, the porous base 560 on which the impregnation process has been completed may be dried at room temperature for 24 hours or more.

According to an exemplary embodiment, the step of forming an adhesive portion on at least a portion of the upper and lower surfaces of the dust collecting filter 580 through the above process may be further included so that the dust collecting filter can be easily attached to the skin adherend.

6 and 7 illustrate a method of using a dust collection filter according to an embodiment.

Referring to FIG. 6, the dust collecting filter 600 may be attached to the fan blade 610. When the fan blade 610 rotates, a rapid flow of air occurs in a direction parallel to the dust collection filter 600, and this flow of air generates triboelectric electricity in the dust collection filter 600, and the dust collection filter 600 generates its electrostatic force. You can use to adsorb fine dust in the air.

7 shows another example in which the dust collecting filter 700 of this embodiment is used. Referring to FIG. 7A, the entire dust collecting filter 700 may be attached to a pin 720 of a ventilator installed in an air conditioner 710 such as an air conditioner. As another example, referring to FIG. 7(b), a part of the dust collection filter 700 is attached to the pin 720 of the air outlet, and the rest of the dust collection filter 700 flows through the air outlet without being fixed. It can be attached in a state that can be shaken according to the flow of air.

In either case of FIGS. 7(a) and 7(b), when the air conditioner 710 is operated, a rapid flow of air occurs in a direction parallel to the dust collection filter 700, and as a result, the dust collection filter ( In 700), triboelectricity is generated, so that fine dust in the air can be effectively adsorbed.

8 illustrates a real picture of a dust collecting filter manufactured in a film form according to an embodiment. The dust collecting filter 800 illustrated in FIG. 8 is manufactured according to the embodiment of FIG. 5 and includes a plurality of pores and fine metal particles.

9 illustrates an experiment result of measuring the performance of removing fine dust by attaching the dust collecting filter of FIG. 8 to a blade of an electric fan. To this end, after generating fine dust by smoking a scented candle in an enclosed space, the fan was operated from a predetermined point in time (Fan on in FIG. 9), and changes in the concentrations of two types of fine dust (PM10, PM2.5) were measured. . Fig. 9(a) shows a case where the fine dust is at a low concentration, and Fig. 9(b) shows a case where the fine dust is at a high concentration. As can be seen from FIG. 9, the dust collecting filter of the present embodiment can effectively lower the concentration of fine dust in both the case where the fine dust is at a low concentration or a high concentration.

10 illustrates a mesh-shaped dust collecting filter 1000 according to an exemplary embodiment, and FIG. 11 illustrates a cross-section A-A′ of FIG. 10.

10 and 11, the dust collecting filter 1000 may be formed in a mesh shape. According to an embodiment, the dust collecting filter 1000 may include a mesh-shaped frame 1050 and a base 1010 surrounding the frame 1050. The mesh-shaped dust collecting filter 1000 may absorb fine dust using triboelectric electricity in both cases where air passes through the dust collection filter 1000 or flows along the dust collection filter 1000.

For example, the frame 1050 may be a screen screen. In this case, the dust collecting filter 1000 has a base coated on the screen, and when air passes through the screen or flows along the side of the screen, it may adsorb fine dust using static electricity.

Alternatively, as an example, the frame 1050 may be a filter having a wider air flow passage than fine dust to be adsorbed. In this case, the dust collection filter 1000 may effectively adsorb fine dust without interfering with the flow of air passing through the dust collection filter 1000.

The base 1010 may comprise a polymer material. The air flow passage between the meshes of the base 1010 may have a size larger than that of fine dust to be adsorbed. For example, the base 1010 may be formed by coating a polymer material on the mesh-shaped frame 1050.

As described above, according to the embodiment, a plurality of pores may be formed in the base 1010. Depending on the embodiment, a dielectric material having a micro or nano size may be dispersed in the base 1010. Depending on the embodiment, a micro- or nano-sized polar material may be dispersed in the base 1010. Depending on the embodiment, a micro- or nano-sized metal material may be dispersed in the base 1010. For pores, dielectric materials, polar materials, and metal materials formed in the base 1010, the above description may be referred to. For example, the dust collecting filter 1000 may be manufactured using the manufacturing method described with reference to FIG. 5. For example, by adding a process of dipping the mesh-shaped frame 1050 into the polymer material 510 in step 5(a) so that the base material is coated on the frame 1050 and the subsequent steps are the same. The mesh-shaped dust collecting filter 1000 may be manufactured.

Meanwhile, in FIGS. 10 and 11, a structure including the frame 1050 is illustrated, but the base 1010 itself may be manufactured in a mesh form without using a frame according to an exemplary embodiment.

Exemplarily, the manufacturing method described with reference to FIG. 5 may be used, but the mesh-shaped dust collecting filter 1000 may be manufactured by forming an air flow passage in the dust collecting filter 580 formed through the step of FIG. 5(f). . For example, by forming an air flow passage through the dust collection filter 580 in the middle of the rectangular parallelepiped dust collection filter 580 formed through the step of FIG. 5(f), the mesh-shaped dust collection filter 1000 will be manufactured. I can.

As an example of another manufacturing method of the mesh-shaped dust collecting filter 1000 that does not include a frame, the manufacturing method described with reference to FIG. 5 is used, but the base material is filled in a mold having a mesh shape in step 5(b). Curing and subsequent steps can be carried out in the same manner.

As described above, the dust collecting filter of the present embodiment has an advantage in that the air flow is not disturbed even if the adsorbed fine dust accumulates by adsorbing fine dust using electrostatic force generated by friction with air. In addition, according to an embodiment, the dust collection filter of this embodiment includes a base formed of a polymer material including at least one of silicone oil, a fluoropolymer, or a composite thereof, and forms a plurality of pores in the dust collection filter or metal nanoparticles. By dispersing the particles, triboelectricity can be easily generated and fine dust can be effectively absorbed.
