▎ 摘　　要

NOVELTY - A graphene aerogel comprises pore structure formed by crosslinking of graphene sheets. The pore wall is composed of several layers of graphene. The cellulose nano crystals obtained by acid hydrolysis are located between the graphene sheets formed on the pore walls or adsorbed on the surfaces. The cellulose nano crystalline orientation arrangement is made to form three-dimensional network structure unit. The composition of graphene aerogel comprises 50-95 wt.% graphene and 5-50 wt.% cellulose nanocrystalline. USE - Graphene aerogel used in remote controller, water treatment, adsorbent material and insulation material (claimed). ADVANTAGE - The graphene aerogel has high strength and wide application range. DETAILED DESCRIPTION - A graphene aerogel comprises pore structure formed by crosslinking of graphene sheets. The pore wall is composed of several layers of graphene. The cellulose nano crystals obtained by acid hydrolysis are located between the graphene sheets formed on the pore walls or adsorbed on the surfaces. The cellulose nano crystalline orientation arrangement is made to form three-dimensional network structure unit. The composition of graphene aerogel comprises 50-95 wt.% graphene and 5-50 wt.% cellulose nano crystalline. The modulus of graphene aerogel is 4-65 kPa. The hydrophilic and lipophilic amphipathic properties, amphiphilic properties and modulus of the aerogel are controlled by changing the content of cellulose nano crystals. INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene aerogel; and (2) usage of graphene aerogel in remote controller, water treatment, adsorbent material and insulation material.
