Abstract

Pulsed Field Gradient NMR (PFGNMR) measurements were performed on a range of PPO-LiSO3CF3 complexes between temperatures of 100°C and 150°C. AC Conductivity and DSC measurements were performed over wider temperature ranges. The ionic conductivity of the samples were measured under constant volume conditions. The impedance measurements were made between the frequencies of 5 Hz and 13 MHz using a Hewlett-Packard HP-4192 impedance meter interfaced to a Zenith 151 computer. The data were analyzed using a model circuit with two complex capacitors, and inductor, and two resistances to accurately determine the bulk resistance. The equation for this circuit algebraically separated into its real and imaginary components.
