▎ 摘　　要

NOVELTY - Manufacturing graphene polymer composite film involves preparing graphene oxide and polymer. The prepared graphene oxide and polymer are mixed in solvent to obtain source solution. The source solution is heat-treated to reduce and burn the graphene oxide to generate graphene and reaction gas. The generated graphene and reaction gas are dispersed in porous polymer matrix produced by foaming to obtain the desired product. USE - Method for manufacturing graphene polymer composite film used for shielding electromagnetic wave (claimed). ADVANTAGE - The method enables to manufacture graphene polymer composite film having high reliability in simple and cost-effective manner.
