Abstract
A method of producing reduced graphene oxide and reduce graphene oxide produced by the method are provided. The method of producing reduced graphene oxide involves forming a graphene oxide-dispersed solution comprising graphene oxide and a surfactant that comprises at least two aromatic functional groups, reducing the graphene oxide-dispersed solution to obtain a layered structure of reduced graphene oxide comprising the at least two aromatic functional groups, and dispersing the layered structure of reduced graphene oxide in a solvent to produce a multi-layered reduced graphene oxide.
