▎ 摘　　要

NOVELTY - Preparing elastic carbon aerogel comprises dispersing graphene oxide in water, stirring, ultrasonically dispersing uniformly, freezing under nitrogen, thawing and ultrasonically treating to obtain oxidized graphene suspension, adding nano microcrystalline cellulose, ultrasonically processing, adding micromolecular carbon source or nitrogen source to obtain graphene oxide/nano microcrystalline cellulose suspension, freezing the suspension under liquid nitrogen, freeze-drying to obtain graphite oxide/nano microcrystalline cellulose composite aerogel, and heating under inert atmosphere. USE - The elastic carbon aerogel is useful in sensors (claimed). ADVANTAGE - The aerogel has low density, high compression, high elasticity and excellent cycle performance. DETAILED DESCRIPTION - Preparing elastic carbon aerogel comprises (a) dispersing graphene oxide in water, stirring, ultrasonically dispersing uniformly, freezing the obtained dispersion liquid under nitrogen, thawing and ultrasonically treating to obtain oxidized graphene suspension, (b) adding nano microcrystalline cellulose into graphene oxide suspension obtained, ultrasonically processing, adding micromolecular carbon source or nitrogen source to obtain graphene oxide/nano microcrystalline cellulose suspension, (c) freezing the suspension under liquid nitrogen, freeze-drying to obtain graphite oxide/nano microcrystalline cellulose composite aerogel, and (d) heating the composite aerogel to 500-850 degrees C for 0-12 hours under inert atmosphere. An INDEPENDENT CLAIM is also included for elastic carbon aerogel, prepared by the above method.
