▎ 摘  要

NOVELTY - Graphene, is prepared by using mechanical exfoliation method and the number of layers of the graphene is not less than 50% with a ratio of not less than 10 layers. USE - Graphene used in sensor, electronic component and biomedicine. ADVANTAGE - The method efficiently prepares high quality of graphene, and the preparation technique is green and environment-friendly, without post-processing, controls different cutting mode to graphite peeling, and uses supercritical carbon dioxide as solvent, and can more efficiently prepare high quality graphene. The graphene has graphene micron-sized sheet diameter and the number of layers is less than 10 layers of the ratio is greatly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the graphene.
