▎ 摘　　要

NOVELTY - A graphene-based aerogel comprises graphene oxide, silicon dioxide, and solvent at mass ratio of 1-10:1-5:95-98. USE - Graphene-based aerogel. ADVANTAGE - The graphite preparation alkenyl gas gel has improved heat insulation performance, and flame retardant effect, and reduces the heat transfer between the gas gel layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-based aerogel comprising adding graphene oxide solution into water to dilute, uniformly stirring to obtain graphene oxide dispersing solution, adding silicon dioxide powder into ethanol solution, uniformly stirring, obtaining silicon dioxide dispersion solution, adding silicon dioxide dispersion solution into graphene oxide solution, uniformly stirring to obtain graphene oxide composite slurry, coating and drying to obtain graphene oxide/silicon dioxide composite film, and processing at 300degrees Celsius for 1 hour. DESCRIPTION OF DRAWING(S) - The drawing shows a heat insulation performance test chart of graphene-based aerogel (Drawing includes non-English language text).
