Electroactive Polymeric Materials for Supercapacitors
Abstract
This program was directed to the use of conjugated and highly electroactive polymers (EAPs) as the active redox materials in electrochemical supercapacitors (SCs). This report summarizes the results that have been obtained between April 2014 and April 2017. We have aimed to take advantage of a major benefit of conjugated electroactive polymers, which is their ability to be room temperature solution processed using roll-to-roll compatible coating methods onto lightweight, flexible substrates of various shapes and sizes. We proposed to (i) develop a family of solution processable dioxythiophene (XDOT) polymers that are easily oxidized and have a broad pseudocapacitive response, (ii) develop soluble polymers that are compatible with aqueous electrolytes using either polar side chains or tethered ionic functionalities, (iii) define structure-property relationships that determine charge storage capacity, discharge rates, and polymer/substrate and polymer/electrolyte interactions, and (iv) incorporate the optimized polymers into various composites either using transition metal oxides or different 3D carbon structures to maximize the pseudocapacitance.
