▎ 摘 要
NOVELTY - A high-thermal conductivity graphene composite film is prepared by adding amine substance and anhydride substance organic solvent, stirring to obtain solution A, taking multiple single layer graphene oxide, dispersing in solution, ultrasonicating at 30-60 degrees C for 5-10 minutes, adding solution A, stirring at 50-80 degrees C, mixing, molding, curing and drying at 50-300 degrees C, putting into plasma ablation machine, and processing for 30-70 seconds. USE - Method for preparing high-thermal conductivity graphene composite film. ADVANTAGE - The product has excellent heat-conducting performance.
