In this paper,graphene/carbon fiber/aramid electromagnetic shielding paper was prepared by combining high-temperature resis-tant aramid chopped fiber and aramid precipitation fiber as paper-based materials,carbon fiber with excellent conductivity as conductive skeleton,and graphene as electromagnetic shielding reinforcement material.The results showed that the prepared graphene/carbon fiber/ara-mid electromagnetic shielding paper had a"sandwich structure".With a thickness of 333.9 μm,the electromagnetic shielding efficiency in X-band was up to 70.3 dB,and the conductivity of 1 685 S/m,and excellent high-temperature resistance and corrosion resistance.
