Supercapacitors have been highlighted as the next generation energy storage devices due to fast charge/discharge rate, high efficiency, and semi-permanent characteristics. When conductive polymers are used as electrode materials, there are advantages differentiated from inorganic materials such as flexible, eco-friendly, safety and low cost. We report a new nanocomposite based on polydopamine (PDA)-capped graphene oxide (PDA-capped GO) and 3,4-ethylenedioxythiophene (EDOT). PDA-capped GO and PEDOT nanocomposites were prepared from one–step coelectrodeposition. During the process of electrochemical polymerization, the anionic PDA-capped GO acted as a weak electrolyte and was entrapped in the conductive polymer nanocomposites. We investigated electrochemical properties, cycling performance and capacitance of PDA-capped GO/PEDOT polymer nanocomposite, and also compared with those of PEDOT. |
