Abstract
A method for manufacturing graphene is disclosed, which comprises the following steps: putting graphite material and an organic solvent, a surfactant, or a combination thereof in a reaction tank and introducing a supercritical fluid in the reaction tank to allow the organic solvent, the surfactant, or the combination thereof to dissolve in the supercritical fluid and to permeate into the graphite material; and removing the supercritical fluid by depressurization to form graphene. The method of the present invention has simple steps and reduced consumption of manufacturing time, and also can promote the quality of the resultant graphene in large-scale manufacturing.
