▎ 摘　　要

NOVELTY - Preparation of polyethylene vinyl acetate composite film comprises preparing graphene oxide through chemical oxidation, reducing graphene oxide at high temperature to graphene, selecting solvent, taking in-situ polymerization at low temperature to prepare composite solution of graphene (5-30%) and polyaniline in mass ratio of 1:2-1:4, preparing polyethylene vinyl acetate solution, mixing with composite solution of graphene and polyaniline, stirring, ultrasonically processing, pouring solution into die, and drying in vacuum to form film. USE - Method of preparation of polyethylene vinyl acetate (claimed). ADVANTAGE - The electrical conductivity of the graphene and polyaniline composite doping materials has been greatly increased and with low cost.
