Abstract

The invention provides a wear-resistant self-cleaning super-amphiphobic coating and a preparation method thereof. A groove-shaped microstructure is constructed on a transparent substrate, and then a nanostructure is grown thereon, and then modified with low surface energy, and finally formed on the transparent substrate. Construction of wear-resistant self-cleaning superamphiphobic coating. The coating of the present invention has a water-oil contact angle of >150°, a rolling angle of <10°, high transparency, excellent abrasion resistance, corrosion resistance, salt spray resistance, aging resistance, good durability, and effectively solves the problem of super double The ubiquitous problems of insufficient light transmittance and mechanical strength in sparse coatings.

Description

Technical field [0001] The present invention relates to the field of nanomaterial preparation, and more particularly to a wear-resistant self-cleaning superb-coating and preparation method. Background technique [0002] The superburge surface is widely used in the exterior wall of the cleaning building, self-cleaning wear equipment, self-cleaning solar panel, car waterproof glass, oil pipeline reduction, electronic device waterproof and other fields. The super surface means that the liquid maintains a large contact angle (> 150 °), a lower rolling angle (<10 °). The current superbievacies are usually enlighten by the lotus leaf surface, which is generally considered to effectively inhibit contact between the liquid and the solid interface by reducing the surface energy and the nanometer roughness on the construction material interface. [0003] The superbound surface is slightly different from a single superhydrophobic surface, and the superbroof surface typically needs to ...
