Abstract:

The preparation of an ion-conducting elastomeric solid based on a dimethylsiloxane-ethylene oxide copolymer complexed with a sodium salt is described. Sodium 23 Nuclear Magnetic Resonance measurements reveal the presence of both bound and mobile sodium species throughout the temperature range -120 to 100 C. Electrical conductivity measurements over a similar temperature range are found to be consistent with the configurational entropy model for transport, with a T sub o parameter about 50 C below the central glass transition temperature T sub g.
