▎ 摘　　要

NOVELTY - Preparing graphene oxide copolymer polycarbonate comprises (i) taking graphene oxide, bisphenol A (BPA) and diphenyl carbonate (DPC) as raw materials, and reacting under the preset conditions to form a prepolymer; and (ii) subjecting the obtained prepolymer to polycondensation reaction. USE - The method is useful for preparing graphene oxide copolymer polycarbonate. ADVANTAGE - The method: prepares graphene oxide copolymer polycarbonate, which has excellent flame-retardant, flexural modulus of more than 50% i.e. higher than that of general-purpose polycarbonate, can be utilized in low temperature environments and is an excellent molding processability engineering material.
