▎ 摘　　要

NOVELTY - Graphene foam comprises polymer sponge comprising multiple pores, and two or more graphene oxide structure containing graphene oxide located inside the pores of the polymer sponge and the graphene oxide structure is arranged parallel to each other. USE - Graphene foam. ADVANTAGE - The graphene foam has controlled graphene arrangement, increased specific surface area, improved sound absorption performance and it is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing graphene foam which involves immersing a polymer sponge including pores in a solution containing graphene oxide to form a polymer sponge containing a graphene oxide solution, forming a graphene oxide structure by cooling the polymer sponge containing the graphene oxide solution, and lyophilizing the cooled polymer sponge to remove moisture to form graphene foam.
