Abstract

The invention provides an acrylamide nano coating and a preparation method thereof. The acrylamide nano coating is characterized in that a substrate is exposed in a monomer steam atmosphere, and a chemical reaction is formed on the surface of the substrate through plasma discharge to form a protective coating; monomer steam is vaporizable monomer 1 or monomer 2, or a mixture of the monomer 1 and monomer 2. Through adoption of the method provided by the invention, a denser and more exquisite micro-convex structure is formed on the surface of the substrate, so that the coating with nano size hasexcellent acid and alkali resistance, corrosion resistance and a super-hydrophobic effect, and a contact angle can reach 150 degrees or above.

Description

technical field [0001] The invention relates to the technical field of plasma chemical vapor deposition, in particular to a nano protective coating and a preparation method thereof. Background technique [0002] As we all know, the low polarizability and strong electronegativity of fluorine atoms in fluorocarbon materials endow fluorocarbon polymers with many unique properties, such as high hydrophobicity and oil repellency, chemical corrosion resistance, excellent weather resistance, etc., so they are widely used In architectural coatings, textile industry, military industry and other fields. Although fluoropolymers have many advantages, their monomers are expensive and difficult to form films using conventional coating methods. CN 106868473 A "Preparation method of liquid-proof coating with gradient decreasing structure" uses plasma chemical vapor deposition technology to successfully deposit fluorocarbon materials containing acrylate structure and multifunctional unsatur...
