▎ 摘　　要

NOVELTY - Graphene oxide is ultrasonically dispersed in water, to obtain graphene oxide dispersion. Cellulose derivative and graphene oxide dispersion are agitated, maintained still and freeze-dried, to obtain graphene oxide/cellulose aerogel. The graphene oxide/cellulose aerogel is reduced using reducing agent, and heat-dried, to obtain highly-elastic graphene composite deformation sensing material. USE - Preparation of graphene composite deformation sensing material (claimed). ADVANTAGE - The method enables preparation of graphene composite deformation sensing material having excellent sensing characteristics and elasticity, and reliable resistance response by simple, efficient and environmentally-friendly method. The highly-elastic graphene composite deformation sensing material restores within 1 second after 70% strain under condition of more than 4000 continuous rapid loading and unloading.
