Conducting polymeric nanocomposite for supercapattery

Abstract Owing to the facile synthesis routes, cost-effective processes, and high specific capacitance with enhanced mechanical stability, the nanocomposites of conductive polymers have gained considerable research attention in the past few years in terms of fundamental research and their successful employment in supercapacitors. Various nanostructured materials such as carbon with its derivatives, metal oxide, transition metal oxide, chalcogenide, and especially the recently developed MXene, when incorporated in conducting polymers show superior electrochemical performance due to the synergistic effect involving both the components. In this chapter, we concentrate on the conducting polymers, highlighting their various types, in addition to that their composites with carbonaceous, chalcogenide, and layered silicate. We briefly discuss the critical issues related to electrodes based on conducting polymers. We have elaborated systematically the electrochemical performances of some nanocomposites of conducting polymers with carbon, metal oxide, MXene, and transition metal dichalcogenide.
