Problems solved by technology

However, there are few reports on the application of conductive polymers to nano-film coatings to improve their antistatic properties.
[0005] Moreover, the current synthesis of conductive polymers is mainly through special chemical catalysts to induce reaction polymerization. The obtained polymers are difficult to process after molding, and it is difficult to compound with other polymers.
When it is combined with a fluorocarbon nano-film coating with hydrophobic and oleophobic properties in order to improve the antistatic performance, it is even more difficult to achieve it using conventional means

Abstract

The invention provides an antistatic and liquid-proof nano-coating and a preparation method thereof, which comprises exposing a substrate to a monomer vapor atmosphere, and chemically reacts on the surface of the substrate through plasma discharge to form a protective coating; the monomer Bulk vapor is a mixture of monomer 1 with a specific structure and monomer 2 with a conjugated structure. The coating prepared by adopting the method of the present application increases the contact angle of the substrate surface, improves the hydrophobicity of the coating surface, and simultaneously obtains good antistatic performance.

Description

technical field [0001] The invention relates to the technical field of plasma chemical vapor deposition, in particular to an antistatic and liquid-proof nano-coating and a preparation method thereof. Background technique [0002] The generation and accumulation of static electricity has brought a lot of troubles to people's daily life and industrial production, and even caused major safety accidents such as fires and explosions. [0003] On the surface of high-precision components such as electronic products, once the static electricity accumulates to a certain extent, it will be affected by the discharge of static electricity, and short-circuit, resistance drift, and work performance degradation will easily occur. Fluoropolymers have the advantages of remarkable hydrophobicity, thermal stability, chemical resistance and oxidation resistance, and are often used as the main component of protective coatings in electrical equipment, transportation equipment, semiconductors and ...
