▎ 摘　　要

NOVELTY - Preparing oxidation-resistant elastic graphene airgel comprises (a) soaking the elastic graphene aerogel in the condensed ring aromatic compound solution to obtain a graphene wet gel, (b) carrying out water activation and freeze-drying to obtain modified graphene airgel, (c) subjecting modified graphene airgel to atomic layer deposition to obtain a modified graphene airgel with a thin layer of aluminum oxide deposited on the surface, and thermal annealing under an inert atmosphere to obtain an aluminum oxide/graphene gas gel, and (d) soaking the alumina/graphene airgel in the polydimethylsiloxane (PDMS) solution, and performing curing and vacuum heat treatment. USE - The method is useful for preparing oxidation-resistant elastic graphene airgel. ADVANTAGE - The anti-oxidation elastic graphene airgel has superelastic properties at room temperature, can still maintain high elasticity in a high-temperature aerobic environment at 1300℃, greatly improves the temperature resistance of graphene airgel to 1300℃ in an aerobic environment.
