Abstract

Vibrational spectroscopic and conductivity data for complexes of NaBF₄ and NaBH₄ with poly(ethylene oxide) indicate that extensive contact ion pairing occurs in the NaBH₄ complex but not in the NaBF₄ complex. As a result the ionic conductivity is considerably lower in the NaBH₄ complex due to trapping of the mobile sodium cations by the anion. Conductivity studies on mixed anion complexes of poly(ethylene oxide) containing both ion-pairing (BH₄⁻) and non-ion-pairing (BF₄⁻) anions suggest that cation transport in these systems is not limited by motion through the polymer helical channels in which the cation is thought to reside. Conduction between helical chains appears to be a dominant process.
