Self-cleaning nano coating

A self-cleaning nano coating has high adhesion ability, high film hardness and toughness, excellent self-cleaning function, high anti-dust and anti-dirt adhesion ability, excellent hydrophobicity and high probability of dirt cleanness and is environment-friendly. The self-cleaning nano coating is prepared from a nano-structure material with an IPN (interpenetrating polymer network) technology. Through simulation of a lotus leaf water repellent principle, invasion of dust and oil dirt is effectively prevented, and pollutants are easily taken away through rainwater washing, so that the coating is clean and looks new for a long time; the self-cleaning nano coating can be applied to surfaces of materials including ordinary glass, organic glass, plastics, ceramics, metals, textile and the like and has a self-cleaning effect.
