▎ 摘　　要

NOVELTY - Graphene conductive elastomer comprises elastic matrix and three-dimensional network structure of graphene. The elastic matrix has holes. The connectivity between the holes is 30-80%.The graphene three-dimensional network structure is filled in the hole. The graphene in the graphene three-dimensional network structure is at least partially an intrinsic graphene or reduced graphene oxide. USE - Used as graphene conductive elastomer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (1) preparing the graphene conductive elastomer, comprising partially interconnecting the holes in the elastic matrix, immersing the elastic matrix in a mold filled with a graphene aqueous dispersion for freeze forming to obtain elastic matrix graphene frozen ice-shaped composite structure, freeze-drying the elastic matrix graphene frozen ice-shaped composite structure at -200 degrees C to -40 degrees C until the graphene frozen ice-shaped structure in the interconnected holes to obtain three-dimensional graphene aerogel network structure; and (2) sensor, comprising graphene conductive elastomer including electrodes. The electrode is connected to the graphene conductive elastomer.
