▎ 摘　　要

NOVELTY - In-situ preparing copper-based fluorinated graphene corrosion-resistant film comprises placing copper substrate in a reaction chamber of chemical vapor deposition equipment, and introducing carbon source gas and hydrogen gas into the reaction chamber to form graphene layer on the surface of the copper substrate by chemical vapor deposition method, introducing fluorine gas and carrier gas into the reaction chamber and performing in-situ fluorination etching treatment on the graphene layer to obtain final product, where the fluoridation etching process is performed at 20-200 degrees C for 5-100 minutes. USE - The corrosion-resistant film is useful for substrate surface protection field (claimed). ADVANTAGE - The method: is simple and safe; adjusts the content of fluorine element and the type of carbon-fluorine bond formation in the copper-based fluorinated graphene corrosion-resistant film by changing the reaction temperature, time, pressure and other conditions. The graphene corrosion-resistant film: has uniform fluorination, high quality, and long corrosion resistance performance cycle; and can be used in rigorous environment including marine.
