Abstract
Abstract 23 Na NMR, electrical conductivity, and DSC studies have been carried out on MEEP complexed with NaCF 3 SO 3 . All results are similar to those for other amorphous ion conducting polymers. Specifically, the NMR spectrum associated with mobile Na + ions exhibits motional narrowing above the glass transition temperature, and activation energies deduced from both T 1 and linewidth measurements reflect localized motion of the actions. The electrical conductivity exhibits the usual non-Arrhenius behavior. However, using previous data for PDMS-EO complexes, it is shown that the VTF or WLF equations are only approximate as the parameters depend upon the temperature range. This sheds light on several discrepancies in the literature.
