▎ 摘  要

NOVELTY - The graphene laminate has an oxidized graphene layer that is located on a metal substrate. A reduced oxidized graphene layer is located on the oxidized oxide graphene layer where the metal substrate is located. The interface between the metal substrate and the oxide graphene layer is formed by chemically bonding a functional group that is bonded to the oxide graphene layer to a metal surface. USE - Graphene laminate for preventing metal corrosion. ADVANTAGE - The metal-corrosion-preventing graphene laminate of the present invention has the effect of simultaneously improving the corrosion resistance while improving the adhesion to metal in forming a coating layer using graphene on the surface of a metal material susceptible to corrosion. The method for producing a metal anti-corrosion-preventing graft laminate can be carried out by a low-temperature heat treatment by introducing a low-cost and large-area coating solution process. A separate binder is not necessary between the metal surfaces, which simplifies the process and reduces the manufacturing cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of the graphene laminate for preventing the metal corrosion. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing the manufacturing method of the metal corrosion-resistant graphene laminate. (Drawing includes non-English language text)
