▎ 摘  要

NOVELTY - Preparation of graphene aerogel involves (s1) preparing graphene oxide slurry, (s2) coating and drying the slurry to obtain graphene oxide film, carrying out chemical reduction foaming treatment to the graphene oxide film, and draining to obtain semi-wet gel, (s3) coating the graphene oxide slurry on the semi-wet gel, drying to obtain graphene aerogel-graphene oxide composite sample, carrying out chemical reduction foaming treatment and draining to obtain semi-wet gel again, (s4) repeating the step (s3) for at least 1 time, and (s4) completely drying the obtained sample. USE - Preparation of graphene aerogel (claimed). ADVANTAGE - The graphene aerogel with large size and adjustable thickness can be cut randomly according to different applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphene aerogel cut without slag omission and transversely torn without delamination.
