Abstract: Disclosed is a graphene laminate including a first graphene layer, containing an electron-donating functional group, and a second graphene layer, disposed on the first graphene layer and configured to include graphene, wherein the second graphene layer is n-doped with the first graphene layer. Thereby, graphene is doped with amino-group-modified graphene, thus preventing the transparency of graphene from decreasing, and the extent of doping of graphene can be adjusted, and the doping effect can last a long time even without any protective layer.
