▎ 摘　　要

NOVELTY - Production of graphene involves forming liquid dispersion comprising dispersing agent, and carbon-based material comprising de-oxidized graphite, and continuously passing liquid dispersion through high-pressure homogenizer comprising inlet, outlet and microchannel having diameter in micrometer scale and connects the space between the inlet and the outlet, such that carbon-based material is formed into graphene having thickness in nanoscale by delaminating while passing through the microchannel with the application of a shearing force. USE - Production of graphene (claimed). ADVANTAGE - The method enables simple production of thin graphene having large surface area, and reduced incidence of defects.
