We synthesize the graphene with the microwave method. Graphite oxide was synthesized via Hummers method with flake graphite as raw material. Graphene is demonstrated to behave as an excellent microwave absorbent, which shows a high specific surface area and good electrochemical performance. The structure of highly oxidized graphite shows a smooth surface with tightly packed sheets. The good structure and excellent performance suggest its promising application in supercapacitors.
