一种自清洁纳米薄膜涂层及其制备方法
A self-cleaning nanofilm coating was prepared by the sol-gel method, combining the properties of nano-silica and titanium dioxide. This solved the problem of dust accumulation on the surface of high-rise glass and solar panels, achieving high light transmittance and self-cleaning effect, and reducing cleaning costs.

AI Technical Summary
Existing technologies are insufficient to effectively address the problem of dust accumulation on the surfaces of high-rise glass and solar panels, leading to decreased light transmittance and high cleaning costs.
A self-cleaning nanofilm coating was prepared using the sol-gel method. By mixing transparent silica sol, nano-silica, nano-titanium dioxide, and a modifier, a nanofilm with hydrophobicity and photocatalytic ability was formed. The photocatalytic properties of nano-titanium dioxide were used to degrade organic pollutants, and the height difference created by silica particles of different sizes increased light reflection.
It achieves a self-cleaning, stain-resistant, and wear-resistant nanofilm coating that maintains high light transmittance and degrades organic pollutants. It is simple to operate, low in cost, and suitable for large-scale production.
