Abstract

The invention relates to a composite anti-fouling film, which is coated on the surface of a substrate material and comprises an inorganic oxide film and a fluorosilicone organic matter thin film, wherein the inorganic oxide film is coated onto the surface of the substrate material; the fluorosilicone organic matter thin film is coated onto inorganic oxide film; the inorganic oxide film is preparedfrom a nanometer silicon oxide and nanometer titanium oxide water solution and ethanol; the volume ratio of the nanometer silicon oxide and nanometer titanium oxide water solution to the ethanol is (1:4)-(1:9); the fluorosilicone organic matter thin film is prepared from fluorosilicone organic matter and HFE (hydrofluoroether); the fluorosilicone organic matter is a solution of a mixture comprising fluoroalkyl ether and active silyl groups, wherein the perfluoroalkyl ether is prepared from 40 to 50 percent of ethyl perfluorobutyl ether and 30 to 40 percent of ethyl nonafluorobutyl ether; therest is silyl group organic matters; the volume ratio of the fluorosilicone organic matter to the HFE is (1:500)-(1:1000).

Description

technical field [0001] The invention relates to the technical field of antifouling films, in particular to a composite antifouling film and a method for preparing and using the same. Background technique [0002] Hydrophobic and oleophobic materials can form a thin film on the outer surface of the substrate material to significantly reduce the surface energy, thereby showing the characteristics of no pollution, low friction, hydrophobicity and oleophobicity. Hydrophobic and oleophobic films play an important role in daily life, including printing and dyeing, food packaging, building materials, anti-fouling, anti-corrosion and anti-oxidation. [0003] The wettability of a solid surface is determined by its chemical composition and microstructure. In general, the chemical composition of its surface plays a decisive role in the wettability of the surface of a solid. Therefore, in order to prepare hydrophobic and oleophobic low surface energy films, low surface energy material...
