METHOD OF REFORMING GRAPHENES BY DISPERSING GRAPHENES INTO A PEROXIDE AQUEOUS SOLUTION AND HEATING THE SAME AND A NANO-COMPOSITE MATERIAL INCLUDING THE SAME

摘要

PURPOSE: A method of reforming graphenes and a nano-composite material including the same are provided to increase hydroxyl groups on a surface and to maximize graphene dispersion and physical properties.;CONSTITUTION: A method of reforming graphenes comprises the following step: dispersing graphenes into 50-100 times of a hydro peroxide solution and heating at 30-100 deg. Celsius. The graphene is manufactured by reducing oxidation graphite. The ratio of the number of carbon to oxygen of the graphenes is 5 or greater. The nano-composite material comprises 0.1-15 parts by weight of graphen powder which is reformed by the method and 100 parts by weight of polymer. The polymer is selected from a group consisting of polyurethane, epoxy resin, polyester, polyamide, polystyrene, poly acrylonitrile, polyethylene, polypropylene and a mixture thereof.;COPYRIGHT KIPO 2013
