Conducting Polymers Composites for Unconventional Solid-state Supercapacitors

Abstract

The rapid development of wearable devices has stimulated the pursuit of unconventional and multifunctional flexible supercapacitors such as stretchable, compressible, electrochromic, self-healable or transparent supercapacitors. Redox-active conducting polymers (CPs) that combine the metal like electrical conductive properties with polymer like mechanical properties are ideal materials for use. However, they suffer from poor performance due to volume variations during the charge and discharge processes. The integration of CPs with other materials to form composites provides an effective approach to achieve excellent performance. This review discusses the recent progress on design and fabrication of CP composites with tailored microstructures for these novel supercapacitors. It will cover a wide range of materials with different intrinsic properties (e.g. carbon materials, metal oxides/hydroxides, two dimensional materials) to be incorporated with CPs. It aims to provide insights into the synergistic effect from components on the supercapacitive performance of composites. We also present the strategies towards their practical applications as integrated systems and the future perspectives.
