Zusammenfassung:The invention relates to a three-dimensional graphene composite material and a preparation method thereof. The preparation method comprises the following steps of mixing graphene oxide, water-solublephenolic resin and water; then, performing hydrothermal reaction for 3 to 24 hours at 120 to 200 DEG C to obtain three-dimensional graphene water gel; after washing and drying, putting the three-dimensional graphene water gel into inert atmosphere; performing heat treatment for 0.5 to 10 hours at 400 to 1000 DEG C to obtain the three-dimensional graphene composite material. 本发明涉及一种三维石墨烯复合材料及其制备方法，所述制备包括：将氧化石墨烯、水溶性酚醛树脂和水混合后，在120～200℃水热反应3～24 小时，得到三维石墨烯水凝胶，洗涤和干燥后置于惰性气氛中，在400～1000℃下热处理0.5～10 小时，得到三维石墨烯复合材料。
