▎ 摘　　要

NOVELTY - Preparing high electromagnetic shielding effectiveness graphene/polymer composite multilayer structure material comprises (i) preparing graphene oxide solution using liquid stripping method, (ii) preparing reduced graphite oxide airgel film, (iii) infiltrating thin layer of polymer on the surface of film, stacking multilayer films together to obtain graphene/polymer composite multilayer structure material. USE - The multilayer structure material is useful in consumer and electronic products, communications equipment, information, security and other civilian and military areas. ADVANTAGE - The method has simple process conditions, easy process flow, low cost and convenient industrial production; and composite material has high strength, high conductivity, corrosion resistance and high electromagnetic shielding effectiveness.
