Electrodeposition of transparent and conducting graphene/carbon nanotube thin films

We report the electrophoretic deposition of graphene/singlewalled carbon nanotube hybrid films onto flexible, transparent and conducting indium tin-oxide-coated polyethylene terephthalate substrates. This room-temperature solution process is completely compatible with polymeric substrates and does not require a sophisticated transfer process, allowing uniform and controllable deposition of such carbon thin films with tailored optical and electrical properties over large areas. In particular, the film thickness, optical transparency and electrical conductivity can be modified by the deposition time and the obtained films span several square centimetres in area.
