System and method for mass production of graphene platelets in arc plasma

Abstract

A system and method for producing graphene includes a heating block, substrate, motor and collection device. The substrate is arranged about the heating block and is configured to receive heat from the heating block. A motor is connected to the substrate to rotate the substrate about the heating block. A cathode and anode are configured to direct a flux stream for deposit onto the rotating substrate. A collection device removes the deposited material from the rotating substrate. A heating element is embedded in the heating block and imparts heat to the heating block. The heating block is made of cement or other material that uniformly disperses the heat from the heating element throughout the heating block. The flux stream can be a carbon vapor, with the deposited flux being graphene.
