NOVELTY - Preparing a highly thermally conductive graphite film inducedpolyimide orientation crystallization involves using graphene and the polyimide composite material as graphite film precursors in the process of high-temperature carbonization and graphitization, using graphene as an orientation and a crystallization inducing agent to promote the graphitization of the polyimide high thermal conductivity graphite film. USE - Method for preparing highly thermally conductive graphite film inducedpolyimide orientation crystallization. ADVANTAGE - The method enables to prepare a highly thermally conductive graphite film inducedpolyimide orientation crystallization has an intrinsic crystalline graphitized carbon structure used as a template for graphitized carbon to induce polyimide molecules during stretching and graphitization, reduces the formation of amorphous defects during the graphitization process, and improves the thermal conductivity and mechanical properties of the graphite film.
