Abstract: Flexible, conductive, graphene-polymer nanocomposites incorporating doped graphene and conductive polymer materials in a layered structure and tunable methods of fabrication are provided. The layered graphene-polymer nanocomposites exhibit resistance quenching by suppressing defect induced carrier scattering in graphene while keeping the optical transmittance greater than 90%, which is essential for many optoelectronic applications. Nanocomposites also demonstrate high mobility and carrier density compared to known TCF materials as well as very low sheet resistance with flexibility of more than ±90 degrees of bending angle. The methods employ layer-by-layer mixed chemical doping strategies that incorporate different doping species to enhance electrical and optical properties individually. The synthesis of the graphene-polymer nanocomposite may be conducted by chemical processes to provide mass production capabilities.
