Graphene Oxide-Doped Polycarbonate Track-Etched Membranes Grafted with Poly(acrylic acid) as Gel Polymer Electrolytes for All-Solid-State Supercapacitors
Track-etched polycarbonate membranes (PC-TeMs) offer a structurally supported and well-defined nanoporous architecture, but their intrinsically low ionic conductivity limits their direct application as solid-state electrolytes in supercapacitors. Here, we grafted poly(acrylic acid) (PAA) into the cylindrical nanopores...
