▎ 摘　　要

NOVELTY - Preparing carbon aerogel material comprises (1) mixing nano cellulose-graphene oxide aqueous dispersion with polymethyl methacrylate solution to obtain nano-cellulose stable oil-in-water Pickering emulsion, (2) freezing Pickering emulsion to obtain the nano cellulose-graphene oxide/polymethyl methacrylate composite aerogel, and (3) annealing nano cellulose-graphene oxide/polymethyl methacrylate composite aerogel to obtain a carbon aerogel material. USE - The method is useful for preparing carbon aerogel material, which is useful in field of electromagnetic shielding and flexible pressure sensing (all claimed). ADVANTAGE - The material: has high compression strain, good fatigue resistance, good electromagnetic shielding and biological sensing performance, wide application prospect in flexible sensor and electromagnetic interference shielding field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for carbon aerogel material.
