GRAPHENE LAMINATE AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to a graphene laminate comprising: a first graphene layer comprising an electron donating functional group; and a second graphene layer positioned on the first graphene layer and comprising graphene, wherein the second graphene layer is n-doped by the first graphene layer. Therefore, the degree at which graphene is doped can be controlled without a deterioration in the transparency of graphene and the doping effect can last for a long time without a protective layer by doping graphene with a graphene modified with an amino group.
