▎ 摘　　要

NOVELTY - Graphene/cellulose composite aerogel comprises graphene modified by polydopamine and cross-linked cellulose non-covalently bonded to polydopamine. The preparation method of graphene/cellulose composite aerogel includes taking graphene and polydopamine solution. The graphene in the polydopamine solution is dissolved to form a graphene/polydopamine gel. A cellulose aqueous solution and a crosslinking agent are added to the graphene/polydopamine gel to form a reaction solution. The reaction solution is freeze-dried to form a graphene/cellulose composite aerogel. USE - Graphene/cellulose composite aerogel used for water purification industry. ADVANTAGE - The graphene/cellulose composite aerogel has good structure, compressibility and support strength.
