NOVELTY - A cellulose/graphene oxide composite aerogel comprises cellulose and graphene oxide at mass ratio of 1:0.1-5. USE - Cellulose/graphene oxide composite aerogel. ADVANTAGE - The composite aerogel has easy to obtain raw materials, uniformly distributed structural pores that can be adjusted within 0.1-500 mu m, specific surface area of up to 10-650 m2/g and can be compressed by 40-90%, density of 0.01-3 g/cm3, good adsorption, and simple, high repeatability, economical and environment-friendly preparation method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite aerogel comprising mixing cellulose and graphene oxide, adding to water, heating while stirring, ultrasonicating, heating while mechanical stirring, foaming, adjusting pressure to obtain bubble-containing aerogel, pouring to a mold, freeze-drying, and cooling with liquid nitrogen.
