▎ 摘　　要

NOVELTY - Manufacturing graphene, comprises: introducing an organic solvent and/or a surfactant, and graphite material in a reaction tank, and introducing a supercritical fluid in the reaction tank to allow the organic solvent and/or the surfactant to dissolve in the supercritical fluid and to permeate into the graphite material; and removing the supercritical fluid by depressurization to form graphene. USE - The method is useful for manufacturing graphene. ADVANTAGE - The method: utilizes the specific supercritical fluid which does not react with graphite and provides graphene that is not surface functionalized and has no defects, thus promoting the quality of the produced graphene; is simple and can be performed within a short period of time and in a large-scale. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing graphene, comprising: introducing graphite material and supercritical fluid into the reaction tank; and removing the supercritical fluid by depressurization to form graphene, and simultaneously to introduce the graphene into an organic solvent, a surfactant-containing organic solvent, or a surfactant-containing aqueous solution.
