Carbon nanomaterials are usually employed for improving the electrical and electrochemical properties of conducting polymer electrodes. However, low-cost of production, scalable simple procedures and adequate integration of the components at the molecular level within the composites become a challenge when dealing with real life applications. In this work, we present a novel strategy for producing graphite nanosheets (GNS) dispersed in the solvent employed then for the chemical synthesis of PEDOT, which allows producing composite nanofilms on plastic substrates for the construction of transparent and flexible all-polymer electrodes. By an optimized experimental procedure, we achieved a proper integration of PEDOT and GNS within ultrathin (
