Abstract

The invention provides a wear-resistant self-cleaning super-amphiphobic coating and a preparation method. A groove type microstructure is constructed on a transparent base material, then a nano structure grows on the groove type microstructure, then low surface energy modification is carried out, and finally the wear-resistant self-cleaning super-amphiphobic coating is constructed on the transparent base material. The water-oil contact angle of the coating is larger than 150 degrees, the rolling angle of the coating is smaller than 10 degrees, and the coating is high in transparency, excellentin abrasion resistance, corrosion resistance, salt spray resistance and aging resistance and good in durability, and effectively solves the common problems of insufficient light transmittance and mechanical strength in a super-amphiphobic coating.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a wear-resistant self-cleaning superamphiphobic coating and a preparation method thereof. Background technique [0002] Superamphiphobic surfaces are widely used in the fields of self-cleaning building exterior walls, self-cleaning wearable devices, self-cleaning solar panels, automotive waterproof glass, oil pipeline drag reduction, and waterproofing of electronic devices. The supersurface means that the liquid maintains a larger contact angle (>150°) and a lower rolling angle (<10°) on the surface. The current superamphiphobic surface is usually inspired by the lotus leaf surface, which is obtained by reducing the surface energy and nanoscale roughness on the interface of the construction material. This design is generally considered to be effective in inhibiting the contact between liquid and solid interfaces. [0003] The super-amphiphobic surface is s...
