▎ 摘　　要

NOVELTY - Methyl acetate solvent is added to reactor, dioctyl diphenylamine and heterocyclic amine are added, pyromellitic dianhydride is added to the resulting mixture, and stirred for 3 hours to obtain polyamic acid solution. Graphene powder is added to the obtained solution, and ultrasonic processing is carried out for 25-35 degrees C to obtain graphene-polyamic acid solution. The obtained solution is paved and scraped on the glass plate, solvent is removed, glass plate is placed in vacuum furnace, and imidized to obtain graphene-mixed polyimide conductive film. USE - Preparation of graphene-mixed polyimide conductive film (claimed). ADVANTAGE - The method provides graphene-mixed polyimide conductive film having reduced surface conductivity. The static electricity of conductive film is prevented.
