METHOD FOR MANUFACTURING GRAPHENE, RING-OPEN GRAPHITE OXIDE AND REDUCED GRAPHITE OXIDE USING THEREOF

摘要

PURPOSE: A manufacturing method of graphene using sulfuric acid, ring breakage graphite oxide manufactured by the same and reduced graphite oxide are provided to cut production costs and the degree of the environmental risks because sulfuric acid used as graphite oxide is inexpensive and has a lower degree of the environmental risk than the conventional reducing agent. CONSTITUTION: A manufacturing method of graphene comprises the steps of: preparing graphite oxide, manufacturing a first mixed solution by mixing graphite oxide with a dispersed agent including sulfuric acid, filtering the first mixed solution to get a first mixture remained, drying the first mixed solution to produce ring breakage graphite oxide and producing reduced graphite oxide from the ring breakage graphite oxide.
