This invention belongs to the field of RGO aerogel technology, specifically disclosing a method for preparing RGO aerogel through hydrothermal synthesis and freeze-drying. This method uses GO sheets, SiC whiskers, and ZIF-67 particles as basic building blocks to prepare RGO aerogel. Using hydrothermal synthesis and freeze-drying techniques, with SiC whiskers as a secondary support network, a graphene composite aerogel with synergistic regulation of N-doped and functional components is constructed.

The RGO-0.10 aerogel prepared by this invention exhibits excellent EMW absorption performance. Furthermore, its highly porous microstructure gives the material a thermal conductivity of 0.03930 W / (m·K), demonstrating good thermal insulation performance.
