▎ 摘　　要

NOVELTY - Preparation of graphene sponge material involves adding nano-zinc oxide to graphene powder, adding nano titanium dioxide and quantum energy nano far infrared powder, mixing at high speed, obtaining mixture (A), adding mixture to the foamed material, stirring, placing the foam in a mold, obtaining sponge and processing resultant sponge at high pressure. USE - Preparation of graphene sponge material (claimed). ADVANTAGE - The method efficiently provides graphene sponge material having excellent adsorption performance, by simple method in short period of time. The graphene sponge material is capable of removing peculiar smell, and releasing negative oxygen ion.
