• Polypyrrole
• Flexible electrode
• Nafion
• Supercapacitor

Flexible electrodes for supercapacitors have been prepared by depositing polypyrrole (PPy) on to a gold-coated PVDF membrane. Specific capacitance values of the order of 380 Fg(-1) for PPy/Nafion and 420 F g(-1) for PPy/p-toluenesulfonate were obtained. For the PPy/Nafion electrode, an energy density of 56 Wh kg(-1) and a power density of 15.50 kW kg(-1) were available after 5000 cycles.
Using a self-contained fully flexible device comprising polypyrrole as both electrodes and a PVDF membrane as separator, a capacitance of 30 F g(-1) was observed after 5000 cycles.
