Abstract

We present the fabrication of three-dimensional graphene structures supported by a polymer scaffold. The structures are fabricated using transfer printing. The structures could have potential applications in electronics, sensing and electrochemical electrodes. Electrochemical measurements confirm an increase in surface area due to the folding of the graphene over the polymer scaffolding. Further, the production method opens the possibility for strain engineering in graphene, opening a wide range of potential novel effects in the physical and chemical properties of graphene.
