Abstract: A coating composition includes a graphene oxide and a solvent. At least one of a carboxyl group and an epoxide group of the graphene oxide is functionalized by an amine. The amine has an activation energy to an epoxide group of the graphene oxide of about −3 kcal/mol to about 8 kcal/mol. A method of forming a stacked structure using the coating composition is provided. A method of manufacturing a display device using the coating composition is provided.
