▎ 摘　　要

NOVELTY - The preparation method of polyimide graphene nanobelts composite material involves hydrocracking carbon nanotubes, drying the resulting product to obtain graphene nanobelts, adding graphene nanobelts to the mixed solution for preparing soluble polyimide film to obtain soluble polyimide, mixing the obtained polyimide with the graphene nanobelts and stirring. USE - Preparation of polyimide graphene nanobelts composite material (claimed). ADVANTAGE - The method enables the preparation of composite material by simple and effective process with improved electrical, mechanical and thermal properties, and ensures the uniform dispersion of graphene nanobelts on the polyimide film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the polyimide graphene nanobelts composite material.
