▎ 摘　　要

NOVELTY - A composite material comprises graphene and metal organic framework. The graphene is three-dimensional porous graphene and the metal organic framework is uniformly grown in internal structure of the graphene. USE - Composite material used as adsorbent, catalyst, or electrode material for supercapacitor assembly, used as electrode material for supercapacitor assembly (all claimed). ADVANTAGE - The composite material has excellent conductivity, performance and capacitance, uniform properties, stable structure and long service life. The method is simple, and economically produces composite material with controlled shape and pore structure. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the composite material, which involves using graphene oxide, solvent, and metal organic framework material precursor solution; and (2) application of composite material as an electrode material for supercapacitor assembly, or mixed with acetylene black and polyvinylidene fluoride (PVDF) in a ratio of 80:10:10 or 85:10:5, as an electrode material for supercapacitor assembly.
