NOVELTY - A solvent and polyimide and graphene raw material are prepared. The prepared raw materials are dispersed in the solvent to form a dispersion containing 2-10 wt.% solid content. The obtained dispersion is spray coated to form polyimide-graphene composite material. USE - Manufacture of polyimide-graphene composite material. ADVANTAGE - The polyimide-graphene composite material is manufactured easily using stable and low viscosity dispersion solution.
