| 摘要 | Disclosed herein is a preparation method of graphene, capable of preparing graphene having a smaller thickness and a large area, and with reduced defect generation, by a simplified process. The preparation method of graphene includes forming dispersion including a carbon-based material including unoxidized graphite, and a dispersant; and continuously passing the dispersion through a high pressure homogenizer including an inlet, an outlet, and a micro-channel for connection between the inlet and the outlet, having a diameter in a micrometer scale, wherein the carbon-based material is exfoliated, as the material is passed through the micro-channel under application of a shear force, thereby forming graphene having a thickness in nanoscale. | ||||||
