▎ 摘　　要

NOVELTY - Preparing polybenzoxazine reinforced three-dimensional graphene foam, comprises dropwise adding benzoxazine monomer-containing organic solution into aqueous graphene oxide solution, mixing uniformly to obtain mixed solution, performing hydrothermal reaction at 80-210 degrees C for 6-48 hours, washing and drying to obtain final product. USE - The polybenzoxazine reinforced three-dimensional graphene foam is useful for preparing three-dimensional graphene aerogel (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for three-dimensional graphene aerogel prepared by annealing polybenzoxazine reinforced three-dimensional graphene foam at 200-1000 degrees C.
