▎ 摘　　要

NOVELTY - Preparation of anisotropic graphene foam comprises preparing graphite oxide; preparing graphene oxide dispersion solution by dispersing graphite oxide into a solvent to prepare graphene oxide dispersion solution; preparing graphene dispersion solution by adding surfactant or reducing agent with certain surface activity into graphene oxide dispersion solution to be used as a protection agent, and preparing graphene dispersion solution through chemical liquid-phase reduction; and damaging a previous graphene stable system. USE - Preparation of anisotropic graphene foam (claimed). ADVANTAGE - The anisotropic graphene foam has specific surface area of 200-2000 m2/g and heat conductivity difference of 2 orders of magnitude in graphene growth direction and in direction, which is vertical to the growth direction.
