Abstract

The invention discloses a polycarbonate-based wear-resistant superhydrophobic coating preparation method. The method comprises dissolving polycarbonate and an antifoaming agent in a solvent to obtain a solution for an intermediate layer, and then dissolving hydrophobic oxide nanoparticles and a low surface energy material in an acetone solution to obtain a solution for a surface layer. In the construction process, a base is coated with commercially available polycarbonate glue, then the glue is coated with the solution for the intermediate layer, and after the solution for the intermediate layer is dried, the intermediate layer is coated with the solution for a surface layer so that the wear-resistant superhydrophobic coating is obtained after drying. Through interaction between the polycarbonate and the acetone solution, the method cleverly realizes the organic combination of the embedded nanostructure and the hierarchical structure, and the thus the prepared superhydrophobic coating has excellent wear resistance.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to a method for preparing a polycarbonate-based super wear-resistant self-cleaning surface. Background technique [0002] The scientific community refers to a surface with a contact angle with water greater than 150° and a sliding angle less than 10° as a superhydrophobic surface. Due to the characteristics of waterproof, self-cleaning, anti-corrosion, and anti-icing, superhydrophobic surfaces are receiving more and more attention and attention in theoretical research and industrial applications. [0003] The preparation of superhydrophobic surfaces often needs to meet the two conditions of suitable roughness and low surface free energy at the same time. Based on this theory, scientists at home and abroad have prepared super-hydrophobic surfaces through various methods and technologies such as imprinting, laser ablation, and sol-gel methods. One problem that currently limits th...
