▎ 摘　　要

NOVELTY - Preparation of graphene aerogels comprises mixing graphene oxide, reducing agent, acrylamide, N,N-methylene bisacrylamide and potassium persulfate to obtain partially reduced graphene/polyacrylamide hydrogel, pre-freezing, reducing partially reduced graphene/polyacrylamide hydrogel to obtain graphene/polyacrylamide hydrogel, dialyzing and drying graphene/polyacrylamide hydrogel to obtain graphene aerogels. USE - Method of preparing graphene aerogels (claimed). ADVANTAGE - The aerogels has uniform cell structure, light, excellent rebound resilience, higher mechanical strength and good solvent resistance, simple and low cost.
