NOVELTY - Preparation of a graphene composite material involves dispersing ultra-high molecular weight polyethylene in a solvent to form a ultra-high molecular weight polyethylene dispersion, adding a graphene dispersion liquid into the polyethylene dispersion, stirring and heating to obtain a spinning solution, spinning, and drafting. USE - Preparation of graphene composite material for polymeric material. ADVANTAGE - The composite material has excellent performance, heat resistance, impact resistance due to excellent strength, UV resistance, cutting resistance and bulletproof function of polyethylene.
