▎ 摘　　要

NOVELTY - A water-dispersible polyaniline/graphene composite material is synthesized by reducing graphene oxide into graphene by hydrazine hydrate; dispersing prepared graphene in solution containing macromolecular dispersing agent; adding aniline for dispersion; dripping oxidizing agent and inorganic acid solution to mixed solution at low temperature, stirring and polymerizing; and centrifuging and washing mixed solution to obtain desired composite material. USE - Method for synthesis of water-dispersible polyaniline/graphene composite material. ADVANTAGE - The prepared composite material can be uniformly dispersed in water, can be stored stably, have no precipitate after placing 6 months, and solve problem that the polyaniline/graphene composite material has difficult in processing.
