Method of preparing graphene nanoplate, prepared graphene nanoplate, graphene nanoplate paste, and conductive layer including the graphene nanoplate

摘要

A method for preparing graphene nanoplate (GNP) is provided and includes preparing expanded graphite (EG) and exfoliating, grinding, or cracking the expanded graphite to crack the EG induced by gas-phase-collision. A graphene nanoplate paste and a conductive coating layer formed of the graphene nanoplate paste are provided and are prepared by the method for preparing graphene nanoplate.
