▎ 摘　　要

NOVELTY - The preparation method of graphene aerogel material involves uniformly mixing graphene oxide and matrix filler and then stirring to obtain precursor solution, adding catalyst to precursor solution, stirring, pouring precursor solution and reinforcing fiber into mold and then sealing, heating the mold to obtain fiber-reinforced graphene hydrogel, adding acetone solution to graphene hydrogel for performing solvent substitution reaction to obtain graphene-ketene gel, taking out graphene-ketene gel and drying to obtain fiber-reinforced graphene aerogel. USE - The method is useful for preparing graphene aerogel material, which is useful as high-temperature insulating material. ADVANTAGE - The method ensures preparation of graphene aerogel material with low thermal conductivity and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene aerogel material prepared by the method.
