DISPERSED GRAPHENE OXIDE REDUCED MATERIAL IN HIGH CONCENTRATION BY CATION-PI INTERACTION AND A MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A dispersed graphene oxide reduced material in high concentration and a manufacturing method of the same are provided to improve the dispersion characteristic of a graphene oxide reduced material solution.;CONSTITUTION: A manufacturing method of a dispersed graphene oxide reduced material includes the following steps of: synthesizing powdered graphite oxide flakes based on powdered graphite flakes; forming a graphene oxide dispersed solution by dispersing the graphite oxide flakes in a solvent; preparing a cation reaction-based graphene oxide dispersed solution by cation-pi interaction caused by positioning cations at the center of alignment which is connected by two-dimensional sp2 bond of carbon atoms in the dispersed solution; and preparing graphene oxide reduced material by reducing the cation reaction-based graphene oxide dispersed solution.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Graphite oxide; (BB) Separation and dispersion; (CC) Cation- interaction graphene oxide(CIGO)
