NOVELTY - Graphene comprises amorphous carbon positioned on the surface with a thickness of less than 10 nm. USE - Used as graphene. ADVANTAGE - The graphene has a high degree of expansion, can improve dispersion characteristics or impart additional functions without impairing properties in the application of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene manufacturing method, comprising preparing a graphite interlayer compound by reacting graphite with an acid, forming a protective layer on the surface of the graphite interlayer compound by reacting the graphite interlayer compound with an organic solvent and expanding and exfoliating the graphite interlayer compound on which the protective layer is formed.
