▎ 摘　　要

NOVELTY - An aqueous dispersion of graphene oxide is added to reactor. A reducing agent or crosslinking agent is added to aqueous dispersion and high-pressure reduced with hot water, to obtain graphene oxide hydrogel. The hydrogel is frozen to -30 degrees C to -10 degrees C and thawed at room temperature, reduced, processed at atmospheric pressure and dried, to obtain graphene aerogel. USE - Preparation of graphene aerogel (claimed). ADVANTAGE - The method enables preparation of graphene aerogel with ultra-large pore and excellent elastic characteristics.
