The present invention relates to a graphene laminate comprising: a first graphene layer comprising an electron donating functional group; and a second graphene layer on the first graphene layer and comprising graphene, wherein , the second graphene layer is n-doped with the first graphene layer. Therefore, the degree of graphene doping can be controlled without deteriorating the transparency of graphene, and without a protective layer doped with graphene modified with amino groups, the doping effect can be lasts a long time. |
