Polymer-based flexible free-standing supercapacitor electrodes are of high interest in energy storage applications due to their lightness, mechanical strength, and high electroactive surface area. Conductive polymers (CPs), like PANI, PPy, PEDOT, and PIn, are preferred for the preparation of flexible electrodes due to their redox-active structures and high specific capacities. To utilize these polymers as flexible supercapacitor electrodes, combining them with flexible support materials like CNTs, graphene and its derivatives, carbon fabric, or nanofibers is a common strategy. These support materials offer mechanical flexibility while enhancing electrode performance by facilitating increased electron transfer. In this respect, polymer support materials are essential in producing flexible electrodes. Studies conducted in recent years prove that the performance of these polymers is increased by combining them with metal oxides or conductive carbon derivatives in hybrid systems. Composites like graphene-PANI, PPy-MnO, and PIn-CNT have significantly advanced supercapacitor applications by providing increased energy and power densities. Moreover, electrochemical properties are evaluated by CV, GCD, and EIS techniques. This study focuses on the role of CPs in preparing flexible electrodes, their synthesis, characterization, and recent studies in this field. Additionally, we evaluate the difficulties encountered in preparing flexible electrodes and their potential contribution to future studies.
