Tunable Nanoscale Structure via Divalent Ion Identity in Charged-Neutral Polymer Blends.

ABSTRACT: Charged-neutral polymer blends, wherein an ion-containing polymer is blended with a neutral polymer, are potential candidates for battery electrolytes due to their improved ion transport properties and electrochemical stability. Though electrostatic interactions in charged polymer blends can theoretically stabilize ordered nanostructures analogous to those observed in neutral block copolymers, direct experimental evidence remains limited. Here, we investigate the effects of divalent cation identity on the nanoscale morphology of charged-neutral polymer blends composed of poly(ethylene oxide) (PEO) and Mg²⁺ or Ca²⁺ ion-containing polymers, poly[3-(methylacryloxy)propylsulfonyl-1-(trifluoromethanesulfonylimide)] (P(Mg(MTFSI)₂) or P(Ca(MTFSI)₂).
