▎ 摘 要
NOVELTY - Preparation of polyethylene-graphene composite, involves (1) carrying out polyethylene surface treatment with a cationic surfactant solution, filtering, drying to obtain surface-treated polyethylene powder, (2) adding surface-treated polyethylene powder to graphene oxide aqueous dispersion, stirring to obtain mixed liquid, (3) spraying mixed liquid at high temperature to obtain polyethylene-graphene mixture powder, (4) adding mixture powder to hydrazine hydrate solution, carrying out reduction reaction, washing and drying to obtain polyethylene-graphene composite. USE - Method for preparing polyethylene-graphene composite (claimed).
