Abstract: A method for enhancing adhesion of a curable composition to a cement-based object includes applying a graphene oxide (GO) containing dispersion on a surface of the cement-based object thereby forming a GO-treated surface on the cement-based object. The method includes disposing the curable composition on the GO-treated surface of the cement-based object. The method includes curing the curable composition by heating thereby forming a GO interfacial layer and an epoxy resin layer. The GO interfacial layer is between the surface of the cement-based object and the epoxy resin layer. The curable composition includes an epoxy monomer and an amine curing agent. The GO interfacial layer has a thickness of from 0.1 to 10 nanometers (nm).
