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 a...

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, which comprises PEDOT / PSS.TiO2 or PEDOT / PSS.TiO2-Er.N, water, an organic solvent, a dispersing agent and a conductivity enhancer, and is prepared by coating with an antistatic super-hydrophilic self-cleaning coating material. According to the invention, the antistatic self-cleaning film can be subjected to super-hydrophilic photocatalytic degradation, has a self-cleaning effect, also can resist static electricity and fouling, and has important significance when being applied to a glass curtain wall or a solar cell; PEDOT / PSS.TiO2-Er.N can introduce a donor energy level and an acceptor energy level into TiO2 at the same time, so that separation of photo-induced electrons and holes can be accelerated, the recombination probability is reduced, and the photodegradation activity is improved; and the coating mode adopted by the invention is spray coating, spin coating, blade coating or roller coating, so thatthe operation is simple, and the method is 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] According to the statistics of relevant departments, nearly 50% of the cities in our country have experienced moderate or above pollution, and 18% of them have experienced severe pollution. A thick layer of air pollution has covered 15% of the country. According to estimates, my country's annual economic loss due to pollution is about 200 billion yuan. These 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...
