Dual-network hydrogel electrolytes based on carboxymethyl cellulose/tannic acid physical network and covalently crosslinked polyacrylic acid for flexible interdigital zinc-ion hybrid supercapacitors.
A rigid-flexible interpenetrating dual-network gel polymer electrolyte (GPE) is designed by integrating a reversible physically crosslinked network of carboxymethyl cellulose (CMC) and tannic acid (TA) - formed via dynamic hydrogen bonds and coordination interactions - with a covalently crosslinked polyacrylic acid (PA...
