An amphiphilic block–graft copolymer electrolyte: synthesis, nanostructure, and use in solid-state flexible supercapacitors

Abstract

A highly ionic conductive amphiphilic nanostructured polymer electrolyte with good flexibility is prepared based on a SBS-<italic>g</italic>-POEM block–graft copolymer. The performance of solid-state flexible supercapacitors based on the SBS-<italic>g</italic>-POEM electrolyte was much higher than that of the widely used conventional PVA/H₃PO₄ electrolyte.
