PROBLEM TO BE SOLVED: To provide a method for manufacturing a separated graphene film, capable of isolating a large amount of graphene films high in quality from graphite at low cost in a single process without a complicated oxidation process.SOLUTION: By applying voltage to graphite electrodes immersed in an electrolyte solution containing an alkali metal salt or an alkaline earth metal salt, such as a potassium salt, or a chloride as an electrolyte to be electrolyzed, graphene films are separated from the graphite electrode. Especially, the applied voltage is a rectangular wave AC. |
