Bi-functional water-born polyurethane-potassium poly(acrylate) designed for carbon-based electrodes of quasi solid-state supercapacitors: Establishing ionic tunnels and acting as a binder

In this study, a sticky copolymer of water-born polyurethane-potassium poly(acrylate) (WPU-PAAK) is designed for acting as not only a gel electrolyte but also a binder in manufacturing the carbon-based electrodes for flexible, quasi solid-state electrical double-layer capacitors (EDLCs). This copolymer has been successfully synthesized from potassium poly(acrylate) backbone cross-linked with water-born polyurethane. In comparison with the most...
