▎ 摘  要

NOVELTY - Preparation of graphene/fullerene hybrid material involves freeze-drying graphene oxide, dispersing graphene oxide in a solvent (s1) to obtain 1-10 mg/mL graphene oxide dispersion liquid, dispersing fullerene in a solvent (s2) to obtain 1-3 mg/mL fullerene dispersion liquid, uniformly mixing graphene oxide dispersion liquid and fullerene dispersion liquid in the mass ratio of 1:1-1:15, magnetically stirring for 0.5-3 hours, placing the mixed dispersion liquid in a polytetrafluoroethylene reactor at 100-220 degrees C for 5-20 hours, washing the resultant and drying. USE - Preparation of graphene/fullerene hybrid material used as electrode for supercapacitor (claimed). ADVANTAGE - The method enables simple and environmentally-friendly preparation of hybrid material. The supercapacitor provided with the hybrid material has high energy storage capacity.
