METHOD FOR PREPARING FEW-LAYER GRAPHENE AND FEW-LAYER GRAPHENE FILM

摘要

Provided is a method for preparing few-layer graphene, which comprises the following steps: (1) providing two carbon electrodes as cathode and anode; and (2) applying a voltage between the two electrodes under a mixed gas atmosphere containing inert gas and gas which is reactive to carbon. Also provided is a method for preparing few-layer graphene film, which comprises the following steps: (1) coating with the solid of few-layer graphene, or mixing the solid of few-layer graphene with solvent to give a solution and then coating with the solution; and (2) heating and reducing the formed film under an atmosphere of inert gas or reducing gas.
