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...
