▎ 摘　　要

NOVELTY - The method for preparing porous three-dimensional graphene material, involves using flake graphite powder as raw material, carrying out microwave treatment of expanded flake graphite powder, adding binder-organic solvent solution, stripping to form graphene sol, adding graphene sol and drying control chemical additives, curing to obtain three-dimensional graphene gel and calcining resulting three-dimensional graphene gel at 400-600 degrees C to obtain porous three-dimensional graphene material. USE - Method for preparing porous three-dimensional graphene material (claimed). ADVANTAGE - The method enables simple preparation of porous three-dimensional graphene material with low production cost.
