    摘要： The present invention relates to a method for preparing graphene which comprises subjecting expanded graphite to high speed homogenization to prepare a feed solution and then subjecting the same to high pressure homogenization, thereby increasing the degree of dispersion of expanded graphite in the feed solution and so improving the efficiency of high pressure homogenization. Therefore, the present method has features that the efficiency of graphene preparation is excellent and the size of graphene to be prepared is uniform, compared with a conventional process.

    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.
