▎ 摘　　要

NOVELTY - Graphite is oxidized and dispersed to obtain anhydrous N,N-dimethyl formamide solution of oxidized graphene. The obtained solution is polymerized using acrylic acid as monomer and benzoyl peroxide as initiator, and composition of oxidized graphene and polyacrylic acid is obtained. The resulting product is reduced to produce graphene. USE - Preparation of graphene. ADVANTAGE - Graphene is easily and economically produced at high yield.
