▎ 摘　　要

NOVELTY - Controlling graphene aerogel pore comprises destroying the orientation of the sheet in the graphene oxide liquid crystal to adjust the pore size of the graphene aerogel, the lower the degree of orientation and the larger the pore size, specifically: using graphene oxide liquid crystal as the precursor of graphene aerogel, destructive graphene oxide liquid crystal layer orientation, directly drying the graphene aerogel precursor after destroying the orientation of the sheet, fixing its orientation structure, adding it in a polar solution containing a foaming agent for plastic foaming, drying to obtain the graphene porous aerogel material. USE - The graphene gradient aerogel is useful in sensing, sound insulation, heat insulation, damping, adsorption, electromagnetic shielding, and wave absorption (claimed). ADVANTAGE - The graphene gradient aerogel greatly promotes the industrialization development. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (1) graphene gradient aerogel where the pore size of the aerogel gradually increases in at least one direction, gradually decreases, or gradually increases or decreases from an intermediate position to both sides; and (2) preparing graphene gradient aerogel comprising placing graphene oxide liquid crystal in a container, destroying the orientation of the sheet on one side or middle position of the graphene oxide liquid crystal, destroying the orientation of graphene aerogel precursor and directly drying sheet to fix its orientation structure, and placing in a polar solution containing a foaming agent for plastic foaming and the graphene gradient can be obtained after drying aerogel.
