Circulation High Duty Ratio Pulse Discharge Multifunctional Nano Protective Coating Method Manufacturing Method

摘要

The method for manufacturing a cyclic high duty ratio pulse discharge multifunctional nano protective coating layer of the present invention belongs to the field of plasma technology, and in the method, a reaction chamber is vacuum pumped and an inert gas is injected to generate a movement of a body, and a monomer vapor is generated in the reaction chamber. Chemical vapor deposition is carried out by injection, and the deposition process includes a pretreatment step and a coating film step. The plasma discharge method of the pretreatment step is a high power continuous discharge, and the plasma discharge method of the coating film step is a large duty ratio pulse discharge, and the pretreatment step The coating film step was repeated at least once, and the effective coating film was increased by allowing more active sites to be drawn into the surface of the substrate due to circulation in the process of the coating film process. It provided multi-layer protection on its own, microscopically showing a more dense coating layer structure, and macroscopically showing excellent hydrophobicity, adhesion, acid-base resistance, mechanical performance, and heat-and-moisture resistance.
