Properties and applications of conducting polymer nanocomposites as electrode materials for supercapacitors

Abstract

Supercapacitors applications can be seen in many proficient used electronics, especially in high-utilization equipment and industrial specific tasks. They are capable to fill power-supply gaps between regular capacitors with considerable power output and batteries owning high energy per mass. Hence the requirements for long endurance supercapacitors developed for complex stand-alone energy storages, microelectronics and sensors among other devices. The polymer nanocomposite polyaniline (PANI) and the spin-off polypyrrole by-product polyethylenedioxythiophene (PEDOT) as electrode materials for supercapacitors make the objects of this study. The investigation of the aforementioned modified nanostructures, in order to obtain valuable informations, was done by scanning electron microscopy and Raman study. Supercapacitors qualities make them the best solution when it comes to applications that require great number of quick charge-discharge cycles, as regenerative braking, burst-mode operations and energy storage on limited periods of time. Nanostructure composites as electrode materials represent the future in terms of safeness and costs for chemical ultracapacitors. This review underlines the prospective qualities and properties regarding polymer composites electrode material.
