Abstract

Polymer electrolytes consisting of poly(ethylene oxide) (PEO) complexed with Cu(CF3SO3)2 have been studied by differential scanning calorimetry (DSC), electron spin resonance (ESR) and ionic conductivity measurements. Although motional effects on the ESR spectra are apparent, the present results cannot distinguish between long range Cu2+ transport or the motion of copper ions attached to polyether segments.
