NOVELTY - Preparation of graphene-doped polyimide film, involves thoroughly mixing the polyamic acid obtained by reacting graphene with a diamine and a dianhydride by a solution mixing method, uniformly coating the mixed polyamic acid on the flat plate by a coater, placing in a high temperature oven for imidization to form the desired polyimide, taking out the product in water and cooling for half an hour, and peeling the polyimide film on the sheet to obtain a desired material. USE - Preparation of graphene-doped polyimide film. ADVANTAGE - The polyimide film has high mechanical strength and remarkable conductivity improvement.
