Flexible and high surface area composites of carbon fiber, polypyrrole, and poly(DMcT) for supercapacitor electrodes

► Thin films of Ppy and poly(DMcT) are electrodeposited on carbon-fiber (CF) cloth. ► Bilayered polymeric composite electrodes are obtained as CF/poly(DMcT)/Ppy. ► The CF/poly(DMcT)/Ppy composite is tested as electrodes for supercapacitors. ► These electrodes present an outstanding specific capacitance value: 1130 ± 100 F g−1. ► The overlaying Ppy film prevents the loss of the poly(DMcT) electroactive material.
