▎ 摘 要
NOVELTY - Producing graphene, comprises (a) ultrasonically dispersing graphite oxide in a polyol solvent, (b) adjusting the pH by adding pH adjusting solution to the solution, and (c) examining microwave pulses at predetermined time intervals. USE - The graphene is useful for producing supercapacitor (claimed), preferably supercapacitor electrode. ADVANTAGE - The method: produces graphene in rapid manner; and heats the solution uniformly. The supercapacitor exhibits improved capacitance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene produced by the above method; and (2) a supercapacitor comprising grapheme.
