▎ 摘　　要

NOVELTY - Preparation of graphene polyimide black film comprises mixing diamine and dianhydride in solvent, subjecting to deoxygenation polymerization reaction to obtain 10-20% solid-containing polyamic acid solution, adding 0.5-5 wt.% graphene oxide, stirring, and imidizing with polyimide. USE - Method for preparation of graphene polyimide black film (claimed). ADVANTAGE - The film has improved mechanical performance, conductive network structure, excellent performance, and simple and low cost preparation method.
