Abstract

Nuclear magnetic resonance (NMR) measurements have been used as a microscopic probe of the static and dynamic behavior of unstretched and stretched films of poly(ethylene oxide)-LiI complexes. The stretched sample was previously reported to exhibit a fivefold increase in the ionic conductivity at ambient temperatures. The NMR data indicate that the origin of this enhancement is likely due to changes in the short and long-range structure which promote ion transport through the helical poly(ethylene oxide) structure. Strong support for this comes from the unexpected observation of an anticorrelation between polymer segmental motion and ionic conductivity enhancement.
