▎ 摘　　要

NOVELTY - A graphene composite aerogel composition comprises 50-90 wt.% graphene oxide, 10-30 wt.% aminated ferroferric oxide and 1-5 wt.% silver nano-wire which are stored independently or in a mixture of two or more. The average diameter of silver nano-wire is 10-20 μm and the average diameter is 100-200 mm. USE - Graphene composite aerogel composition used in materials such as electromagnetic shielding material, adsorption material or phase change (all claimed). ADVANTAGE - The graphene composite aerogel has a stable three-dimensional structure, and has the characteristics of light weight, large specific surface area and strong adsorption capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1.preparation of graphene composite aerogel, which involves (s1) mixing graphene oxide, aminated ferroferric oxide, and silver nanowires in presence of solvent to obtain mixed solution (A), heating to obtain mixed solution (B), (s2) performing contact reaction with the mixed solution (B) and L-ascorbic acid to obtain a hydrogel, and (s3) subjecting the hydrogel to freezing treatment and drying; and 2.graphene composite aerogel.
