Embodiment 1

[0026] An organic-inorganic hybrid antistatic self-cleaning film, the film layer mainly includes PEDOT / PSS TiO 2, this film was spin-coated from an antistatic superhydrophilic self-cleaning coating.

[0027] The preparation method of the organic-inorganic hybrid antistatic self-cleaning film comprises the following steps:

[0028] A. Treatment of the base: Clean the surface of the curtain wall glass to remove dust and oil on the surface;

[0029] B. Preparation of antistatic superhydrophilic coating: Add 5mL acetylacetone and 10mL butyl titanate dropwise to 100mL ethanol under magnetic stirring, then add concentrated nitric acid dropwise to adjust the pH to 2.5, stir for 3 hours, seal and let it stand for aging 8h, get TiO 2 Sol. TiO 2 Add the sol dropwise to 0.1mol / L PSS (polystyrene sulfonate) aqueous solution, stir, then add EDOT (3,4-ethylenedioxythiophene) monomer, add concentrated nitric acid dropwise to adjust the pH of the solution to 2.5, add (NH 4 )S 2 o 8 an...

Embodiment 2

[0033] An organic-inorganic hybrid antistatic self-cleaning film, the main component of the film layer is PEDOT / PSS TiO 2 -Er.N, also includes additives such as dispersant and conductivity enhancer. The films were spin-coated from antistatic superhydrophilic self-cleaning coatings.

[0034] The preparation method of the organic-inorganic hybrid antistatic self-cleaning film comprises the following steps:

[0035] A. Treatment of the base: Clean the surface of the curtain wall glass to remove dust and oil on the surface;

[0036] B. Preparation of antistatic superhydrophilic coating: Add 5mL acetylacetone and 10mL butyl titanate dropwise to 100mL ethanol under magnetic stirring, then add concentrated nitric acid dropwise to adjust the pH to 2.5, stir for 3 hours, seal and let it stand for aging 8h, get TiO 2 solution. Erbium nitrate Er(NO 3 ) 3 Add the TiO 2 Stir in the sol for 24h to obtain the TiO solution doped with erbium 2 solution. Add this solution dropwise to a...

Abstract

The invention relates to an organic-inorganic hybrid antistatic self-cleaning film, and the antistatic self-cleaning film comprises PEDOT / PSS TiO 2 or PEDOT / PSS TiO 2 ‑Er.N, water, organic solvent, dispersant and conductivity enhancer, the antistatic self-cleaning film is prepared by coating with antistatic super-hydrophilic self-cleaning coating. The antistatic self-cleaning film can not only be degraded by superhydrophilic photocatalysis, play a role of self-cleaning, but also can be antistatic and antifouling. It is of great significance to be applied to glass curtain walls or solar cells; PEDOT / PSS TiO 2 ‑Er.N, can be in TiO 2 The introduction of donor energy level and acceptor energy level in the same time can accelerate the separation of photogenerated electrons and holes, reduce the probability of recombination, and increase the photodegradation activity; the coating method used in the present invention is spray coating, spin coating, blade coating or roller , easy to operate and suitable for industrial production.

Description

technical field [0001] The invention relates to an organic-inorganic hybrid antistatic self-cleaning film and a preparation method thereof, belonging to the technical field of organic-inorganic semiconductors. Background technique [0002] The increasingly serious smog, oily smog, industrial waste gas, vehicle exhaust, and acid rain have brought a lot of pollution problems to the exterior walls of buildings, greatly affecting the aesthetics, functionality, and durability of buildings. Stain resistance has become an important index to investigate the performance of building exterior wall coatings. The solar cell industry is also facing the same problem. At present, the application of solar cells in various countries in the world is increasing rapidly, and the light transmittance of general glass is about 90%. Dust, pollen, oil, bird droppings, etc. adhere to the surface and the transmittance drops to 50-70%, thereby reducing the power generation rate, and the uneven adhesio...
