Abstract

A method for preparing a topological structure titanium dioxide superhydrophobic material. The invention relates to a preparation method of a superhydrophobic material. The invention aims to solve the problems of poor hydrophobic performance, poor mechanical performance, insufficient durability and narrow application range of existing superhydrophobic materials. Methods: 1. Growth of topological structure titanium oxide; 2. Modification of topological structure surface with low surface energy substances. The invention is used for the preparation of topological structure titanium dioxide superhydrophobic material.

Description

technical field [0001] The invention relates to a preparation method of a superhydrophobic material. Background technique [0002] The lotus leaf in nature can keep the surface clean, and its surface micro-nano composite structure endows the surface of the lotus leaf with excellent superhydrophobic properties, so that the dust and other attachments on the lotus leaf can be easily taken away by water. Superhydrophobic materials are widely used in anti-corrosion, electrode diaphragm, oil-water separation, anti-fog and de-icing, anti-fouling and dust removal and other fields. The methods for preparing the surface of superhydrophobic materials are mainly divided into two categories: one is to reduce the surface energy of solids by modifying low surface energy substances; the other is to construct micro-nano composite structures to change the roughness of solid surfaces. Depositing a hydrophobic film on a polyimide film using the existing technology generally has problems such a...
