New Polymer Electrolyte Hosts and Their Tetrabutylammonium Chloride Complexes. Relationships Among Concentration of Polar Groups, ESR Spin Probe Response, and Ionic Conductivity.
Abstract
A new polymer electrolyte host was synthesized by hydrosilation of a poly(hydromethylsiloxane) with terminal olefin bearing a silyl ketene acetal. The derivatized siloxane was subsequently reacted with 4-nitrobenzenesulfenyl chloride, affording polymers having highly polar pendants. Complexes of these polymers with tetrabutylammonium chloride were prepared. The ionic conductivities of these materials are a function of concentration of polar pendent groups and, as a result, the glass transition temperature. The weak dependence of polymer host Tg on tetrabutylammonium chloride concentration makes these ideal model systems to explore the factors which ultimately limit ionic conductivity.
