NOVELTY - Manufacture of graphene involves supplying a graphite feed solution containing dye, into a high-pressure homogenizer comprising a microchannel connecting an inlet and an outlet. The graphite feed solution includes an intramolecular anthraquinone, triphenylmethane, azobenzene or phthalocyanine structure, and has a sulfonate group. USE - Manufacture of graphene (claimed). ADVANTAGE - The method enables efficient manufacture of graphene with excellent dispersion stability and separation efficiency.
