  • Method for continuously mass-manufacturing graphene using high-temperature plasma emission method and graphene manufactured by manufacturing method
    Patent number: 11697593
    Abstract: A method for continuously mass-manufacturing graphene using thermal plasma, the method for continuously mass-manufacturing graphene includes the steps of: (a) injecting an inert gas into a plasma device to generate plasma; (b) injecting expandable graphite and graphite intercalation compounds (GIC) into the plasma device in constant amounts; and (c) allowing the expandable graphite and GIC to be expanded by thermal plasma treatment so that graphene is exfoliated.
