▎ 摘　　要

NOVELTY - Preparing ferrous chloride modified graphene magnetic composite material involves providing an aqueous solution of ferric chloride, adding graphene oxide dispersion liquid into the ferric chloride aqueous solution, oxidizing to obtain the ferrous chloride modified graphene oxide composite material, and subjecting the ferrous chloride modified graphene oxide composite material for thermal reduction to obtain the ferrous chloride modified graphene magnetic composite material, where the thermal reduction is carried out in a protective atmosphere. USE - The method used for preparing ferrous chloride modified graphene magnetic composite material. ADVANTAGE - The method enables preparation of ferrous chloride-modified graphene magnetic composite material by simple method.
