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.

Graphene laminate and preparation method therefor

Disclosed herein is a laminate comprising: a substrate; an organic surface modifying layer disposed on the substrate; and a porous organic semiconductor layer disposed on the surface modifying layer. Onto the substrate, introduction of the organic surface modifying layer having a low surface energy, and optionally the organic intermediate layer having a low glass transition temperature controls the self assembly of the organic semiconductor layer, allowing the porous organic semiconductor layer to have high crystallinity and large crystal grains. Also, provided is a highly efficient chemical sensor comprising the laminate.
