▎ 摘　　要

NOVELTY - Preparing composite material comprises using polymethyl methacrylate (PMMA) prepolymer to soak graphene aerogel, and then performing in-situ polymerization to the PMMA prepolymer to prepare graphene aerogel/PMMA composite material. USE - The composite material is useful for controlling PMMA structure based on graphene aerogel skeleton (claimed). ADVANTAGE - The composite material: can realizes pre-construction of graphene three-dimensional network and pore structure through the preparation of graphene aerogel, and then which is infiltrated by PMMA prepolymer and molded in a mold with a shape to prepare PMMA/graphene composite material; has good electrical and thermal conductivity, and can improves the utilization of graphene performance.
