PRODUCTION METHOD FOR GRAPHENE

摘要

The present invention relates to a graphene production method which makes it possible to use a simplified process in order to produce graphene which has a relatively thin thickness and large surface area and has a reduced incidence of defects. The graphene production method comprises: a step of forming a liquid dispersion comprising a dispersing agent and a carbon-based material comprising unoxidised graphite; and a step of continuously passing the liquid dispersion through a high-pressure homogeniser comprising an inlet, an outlet and a microchannel that has a diameter on the micrometre scale and connects the space between the inlet and the outlet, and the carbon-based material is formed into graphene having a thickness on the nanoscale by being delaminated while passing through the microchannel with the application of a shearing force.
