▎ 摘　　要

NOVELTY - Manufacturing reduced graphene oxide, comprises (a) preparing a dispersion liquid containing graphene oxide and surfactant containing at least two aromatic functional groups, (b) obtaining reduced graphene oxide laminate containing at least two aromatic functional groups by reducing the dispersion liquid, and (c) dispersing the reduced graphene oxide laminate in an aqueous solvent to obtain multilayered reduced graphene oxide, where the aromatic functional group includes naphthyl group, anthracene group, pyrene group and/or tetrahydropyrene group. USE - The method is useful for manufacturing reduced graphene oxide (claimed). ADVANTAGE - The method completely removes surfactant by repeatedly washing with solvent without affecting graphene characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the reduced graphene oxide manufactured by the above method.
