▎ 摘  要

NOVELTY - A polyimide paint comprises a polyamic acid solution obtained by in-situ polycondensation of aromatic dianhydride, aromatic diamine and fluorinated amino graphene. USE - The polyimide paint is useful for high heat-resistant enameled wire (claimed) for electronic appliances, household appliances and instrument equipment. ADVANTAGE - The polyimide paint provides high heat-resistant enameled wire, which has excellent mechanical property, high temperature durability, and low dielectric loss. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high heat-resistant enameled wire, which is prepared by immersing a metal wire in the polyimide paint, coating the polyimide paint of the desired thickness on the surface of the metal wire, and treating at high temperature.
