We report a fabrication process of foldable graphene nanoplatelet (GNP) patterns on paper substrates. Conductive patterns were prepared on paper by drop casting of a dispersion of GNPs on glossy paper and pen transfer printing from the back of the glossy surface to another paper substrate. The low adhesion between the glossy surface and GNPs promotes the transfer of the GNPs to a receiving rougher paper substrate. The proposed method is convenient for depositing foldable conducting GNP line patterns.
