Technical Field

[0001] The present invention relates to a manufacturing method and a cleaning method, in particular to a manufacturing method of a light-triggered cleaning light-transmitting structure and a cleaning method of a light-triggered cleaning light-transmitting structure. Background Art

[0002] Traditional antibacterial, antimicrobial or sterilizing glass is usually coated with a layer of sterilizing material (such as silver, copper, zinc and other metals with sterilizing functions) on the surface of the glass. The sterilizing material itself can destroy viruses or bacteria to achieve the sterilization effect.

[0003] However, the sterilization material coated on the glass surface usually has color (for example, silver appears slightly yellow, zinc appears bluish silver, etc.), which not only reduces the light transmittance of the glass, but also causes color difference, which does not meet the use requirements. Furthermore, the sterilization material coated on the glass surface by coating usually wears out, abrades or peels off after long-term use, which leads to a significant decrease in the sterilization ability of the glass.

[0004] In addition, during the manufacturing process of the above-mentioned glass, the cleanliness requirements of the environment and the manufacturing process are very high, and the manufacturing process is very complicated, resulting in the problem of excessively high manufacturing costs of the above-mentioned glass. Summary of the invention

[0005] The main purpose of the present invention is to solve the problems of light transmittance and color difference of traditional coated sterilization glass, and to solve the problem that the life of the coating is reduced due to contact wear and long-term exposure to light, resulting in reduced sterilization ability.

[0006] To achieve the above-mentioned purpose, an embodiment of the present invention provides a method for manufacturing a light-triggered cleaning translucent structure, which comprises the following steps: Step S1: providing a translucent substrate, the translucent substrate having a surface; Step S2: forming a nanoparticle layer on the surface, the nanoparticle layer having a plurality of nano-metal particles; Step S3: heating the translucent substrate to a softening temperature and continuing the heating time so that the translucent substrate is in a softened state and the nano-metal particles penetrate into the translucent substrate; Step S4: lowering the temperature of the translucent substrate doped with nano-metal particles to room temperature so that the nano-metal particles form a doping structure in the translucent substrate to form a light-triggered cleaning translucent structure.

[0007] In another embodiment of the present invention, the material of the light-transmitting substrate is an insulating material.

[0008] In another embodiment of the present invention, the material of the light-transmitting substrate is glass.

[0009] In another embodiment of the present invention, the nano metal particles are nano-sized metal materials or metal oxide materials.

[0010] In another embodiment of the present invention, the softening temperature is the softening point temperature of glass.

[0011] In another embodiment of the present invention, the heating time is between 3 and 20 minutes.

[0012] In another embodiment of the present invention, the material of the light-transmitting substrate is an amorphous high molecular polymer.

[0013] In another embodiment of the present invention, the nano-metal particles are nano-sized metal oxide materials.

[0014] In another embodiment of the present invention, the softening temperature is between the glass transition temperature (Tg) and the viscous flow temperature (Tf) of the amorphous polymer.

[0015] In another embodiment of the present invention, in step S4, the nano-metal particles themselves or with surrounding material molecules generate grain boundaries, and the nano-metal particles combine with the grain boundaries to form a doping structure.

[0016] Furthermore, the present invention further discloses a cleaning method for a light-triggered cleaning translucent structure, which comprises the following steps: Step S5: irradiating a light source on the light-triggered cleaning translucent structure, the light source causes surface plasmon polaritons to form on the surface of the nano-metal particles of the doped structure, and Tam plasmon polaritons to form at the grain boundaries of the doped structure, and the surface plasmon polaritons and the Tam plasmon polaritons resonate with each other and form an optical Tam state; Step S6: the optical Tam state can interact and oscillate with the surrounding substances of the light-triggered cleaning translucent structure and form a cleaning substance, which diffuses outward from the periphery of the light-triggered cleaning translucent structure to remove pollutants around the light-triggered cleaning translucent structure.

[0017] In another embodiment of the present invention, the wavelength of the light source is between 100 and 1000 nanometers.

[0018] In another embodiment of the present invention, when the material of the light-transmitting substrate is glass, the wavelength of the light source is between 320 and 570 nanometers.

[0019] Therefore, the light-transmitting structure made by the present invention is transparent inside the light-transmitting structure due to its doping structure, and the cleaning substances generated by the doping structure can diffuse toward the surrounding space of the light-transmitting structure. Therefore, the light-transmitting structure can maintain the transmittance and improve the sterilization ability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to facilitate the description of the central idea of ​​the present invention in the above content, a specific embodiment is used here to express the present invention. It is stated that various objects in the embodiments are drawn according to a proportion suitable for enumeration and description, rather than according to the proportion of the actual components.

[0026] Figures 1 to 5 The figure shows a method 100 for manufacturing a light-triggered cleaning light-transmitting structure according to an embodiment of the present invention. The method 100 comprises the following steps:

[0027] Step S1: Provide a light-transmitting substrate 10, wherein the light-transmitting substrate 10 has a surface 11. In the embodiment of the present invention, the material of the light-transmitting substrate 10 is an insulating material and is glass or an amorphous polymer, wherein the main component of the glass is silicon oxide, but the present application does not exclude the use of other transparent oxide materials; the amorphous polymer may be polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyetherimide (PEI), polyphenylene sulfide (PPS), polyvinylidene chloride (PVDF) , polytetrafluoroethylene (PTFE), polyphenylene ether sulfone (PES), polyamide resin, styrene-acrylonitrile copolymer (AS), polypropylene (PP), polyvinyl chloride (PVF), polyvinylidene chloride (PVDC), polysulfone (PSF), polyphenylene ether (PPO), polycarbonate (PC), polyphenylene sulfide (PPS), chlorinated polyether, polyarylate (PAR), polyetheretherketone (PEEK), polyimide (PI), epoxy resin (EP), phenolic resin (PF), polyphenyl ester, polyetherimide (PBI), polyetheramineimide (PAI), etc., and the transmittance of the amorphous polymer is more than 50%.

[0028] Step S2: forming a nanoparticle layer 20 on the surface 11 of the transparent substrate 10. The nanoparticle layer 20 has a plurality of nano-metal particles 21 (such as Figure 3 As shown). In the embodiment of the present invention, when the light-transmitting substrate 10 is glass, the nano-metal particles 21 may be nano-sized metal materials or metal oxide materials; when the light-transmitting substrate 10 is an amorphous polymer, the nano-metal particles 21 are nano-sized metal oxide materials. The metal material may be gold, silver, copper, zirconium, aluminum, lithium, nickel, zinc and other metals; the metal oxide material may be indium oxide, indium tin oxide, indium gallium zinc oxide, fluorine-doped tin oxide, silicon-doped zinc oxide and other transparent conductive metal oxides.

[0029] Furthermore, when the light-transmitting substrate 10 is glass, since glass has high heat resistance and scratch resistance, the nanoparticle layer 20 can be formed on the light-transmitting substrate 10 by evaporation, sputtering, chemical vapor deposition, coating, scraping or rolling. When the light-transmitting substrate 10 is an amorphous polymer, since amorphous polymers generally have low heat resistance and scratch resistance, preferably, the nanoparticle layer 20 is formed on the light-transmitting substrate 10 by coating, spraying, scraping or rolling, and before performing the step of forming the nanoparticle layer 20, an additive (such as an organic solvent such as acetone and toluene) can also be coated on the light-transmitting substrate 10 to increase the adhesion between the nanoparticle layer 20 and the light-transmitting substrate 10 through the additive.

[0030] Step S3: heating the transparent substrate 10 to a softening temperature and continuing the heating time to soften the transparent substrate 10 and allow the plurality of nano-metal particles 21 to penetrate into the transparent substrate 10 (eg Figure 4 As shown). In the embodiment of the present invention, when the transparent substrate 10 is glass, the softening temperature is the softening point temperature of the glass (about 650°C to 750°C); when the transparent substrate 10 is an amorphous polymer, the softening temperature is between the glass transition temperature (glass transition temperature, Tg) and the viscous flow temperature (viscous flow temperature, Tf) of the amorphous polymer; when the transparent substrate 10 is glass, the heating time is between 3 and 20 minutes.

[0031] Furthermore, when the transparent substrate 10 is in a high temperature softened state, the molecular motion in the transparent substrate 10 will be intensified due to the high temperature, and the penetration speed of the plurality of nano-metal particles 21 will also increase due to the intensified molecular motion. During the penetration process of the plurality of nano-metal particles 21, the nano-particle layer 20 will gradually disappear.

[0032] Step S4: lowering the temperature of the transparent substrate 10 doped with the plurality of nano-metal particles 21 to room temperature, so that the plurality of nano-metal particles 21 form a doping structure 30 in the transparent substrate 10, thereby forming a light-triggered cleaning transparent structure 1 (such as Figure 5 As shown). In the embodiment of the present invention, the plurality of nano-metal particles 21 themselves or with the surrounding material molecules generate grain boundaries, and the plurality of nano-metal particles 21 combine with the grain boundaries to form the doping structure 30. To further explain, the grain boundary can be formed in the nano-metal particle 21 itself, at the junction of the periphery of the nano-metal particle 21, or at the position where the surrounding material molecules have wrinkles and deformations due to the doping and extrusion of the nano-metal particle 21.

[0033] The present invention also provides a cleaning method 200 for cleaning a light-transmitting structure using light-triggered cleaning, which comprises the following steps:

[0034] Step S5: irradiating a light source on the light-triggered cleaning transparent structure 1, the light source causes surface plasmon polaritons (SPP) to be formed on the surfaces of the plurality of nano-metal particles 21 of the doped structure 30, and Tamm plasmon polaritons (TPP) to be formed at the grain boundaries of the doped structure 30, and the surface plasmon polaritons and the Tamm plasmon polaritons resonate with each other and form optical Tamm states (OTS).

[0035] Among them, the wavelength of the light source is between 100 and 1000 nanometers; in another preferred embodiment, when the material of the transparent substrate 10 is glass, the wavelength of the light source is between 320 and 570 nanometers, and the preferred wavelength may be between 350 and 450 nanometers. The use of this violet-biased light source can improve the generation efficiency of the surface plasmon polaritons and the Tamm plasmon polaritons.

[0036] Step S6: The optical Tamm state can interact and oscillate with the surrounding substances of the light-triggered cleaning light-transmitting structure 1 to form a cleaning substance, which diffuses outward from the periphery of the light-triggered cleaning light-transmitting structure 1 to remove pollutants around the light-triggered cleaning light-transmitting structure 1. For example, the surrounding substances can be water vapor, and the cleaning substance is the hydrogen ions (H 2+) dissociated from the water vapor through the interaction and oscillation with the optical Tamm state. + ) and hydroxide ions (OH - ), so that the cleaning substance can remove the pollutants on the surface of the light-triggered cleaning light-transmitting structure 1. It should be noted that the dissociated hydrogen ions (H + ) and hydroxide ions (OH - ) will not only exist on the surface of the light-triggered clean light-transmitting structure 1, but will further expand into the air through diffusion or floating to achieve the purpose of removing pollutants. For example, the surrounding substance can be oxygen, and the cleaning substance is oxygen that interacts with the optical Tamm state to obtain super oxygen molecules (·O2 - ) and oxygen ions (O 2- ).

[0037] Furthermore, if the pollutant is a virus, bacteria or mold, the cleaning substance can directly eliminate the pollutant from the surrounding environment of the light-triggered cleaning light-transmitting structure 1, for example, by hydrogen ions (H + ) and hydroxide ions (OH - ) can destroy bacteria or viruses; if the pollutants are suspended particles, such as PM10, PM2.5 or haze, the cleaning material can capture the pollutants and cause them to aggregate and settle on the ground, thereby reducing the probability of the pollutants accumulating on the surface of the light-triggered cleaning translucent structure 1.

[0038] Therefore, the present invention has the following advantages:

[0039] 1. The light-triggered clean light-transmitting structure 1 manufactured by the present invention has a doping structure 30 that is transparent and colorless. Therefore, the light-triggered clean light-transmitting structure 1 has the advantages of high transparency, high light transmittance, and no color difference.

[0040] 2. The nano-metal particles 21 used in the present invention are not limited to metals that have sterilization functions themselves, and general metals can also be used. Therefore, it has the advantages of high flexibility and low cost.

[0041] 3. The light-triggered clean light-transmitting structure 1 made by the present invention has a doping structure 30 formed inside the structure and not exposed outside the structure. Therefore, it does not have a long-term use and will cause wear and tear and reduced sterilization ability.

[0042] 4. The cleaning substance produced by light irradiation of the present invention can diffuse outward from the periphery of the light-triggered cleaning light-transmitting structure 1, thereby effectively expanding the overall cleaning range and improving the overall sterilization ability.

[0043] Although the present invention is described with a preferred embodiment, those skilled in the art can make various changes without departing from the spirit and scope of the present invention. The above embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. All modifications or changes that do not violate the spirit of the present invention are within the scope of the present invention.
