▎ 摘　　要

NOVELTY - Manufacture of graphene-carbon nanotube hybrid sponge involves (a) preparing carbon nanotube sponge, (b) preparing polystyrene microspheres, (c) preparing graphene oxide-coated polystyrene microspheres, (d) dispersing the graphene-coated polystyrene microspheres in an aqueous solution, and (e) vacuum infusing graphene-coated polystyrene microspheres into carbon nanotube sponge, and freeze-drying to obtain graphene polystyrene microspheres/carbon nanotube sponge materials, and (f) heating the obtained graphene/polystyrene microsphere/carbon nanotube sponge material, removing polystyrene microspheres, and reducing graphene oxide. USE - Manufacture of graphene-carbon nanotube hybrid sponge. ADVANTAGE - The method enables the effective manufacture of graphene-carbon nanotube hybrid sponge having excellent specific surface area, conductivity of carbon nanotube sponge and electromagnetic shielding effect by introducing graphene in carbon nanotube sponges.
