▎ 摘　　要

NOVELTY - Preparation of three-dimensional graphene composite, involves mixing graphene oxide, a water-soluble phenolic resin, and water, hydrothermally reacting at 120-200 degrees C for 3-24 hours to obtain a three-dimensional graphene hydrogel, washing the hydrogel, drying, and heating at 400-1000 degrees C in an inert atmosphere for 0.5-10 hours. USE - Preparation of three-dimensional graphene composite (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for three-dimensional graphene composite having a density of 0.1-600 mg/cm3, a specific surface area of 100-800 m2/g, and a sheet resistance of 0.5-8 Omega /square.
