PREPARATION AND ELECTRICAL RESPONSE OF SOLID POLYMER ELECTROLYTES WITH ONLY ONE MOBILE SPECIES

Ionic conductivity has been induced in the quaternary ammonium polymer poly(diallyldimethylammonium) with chloride or (trifluoromethyl)sulfonate counterions by the introduction of a plasticizer, poly(ethylene glycol) (PEG). Similarly, sodium poly(styrene-sulfonate) becomes a sodium ion conductor when plasticized with PEG. Ion transport properties in these materials are similar to those of the well-known class of solid electrolytes poly(ethylene oxide)-alkali metal salt complexes, except that the ac and dc electrical properties can be attributed to known charge carriers. Conductivity of 10** minus **5 OMEGA ** minus **1 cm** minus **1 at 25 degree C has been achieved for the highly plasticized chloride ion conductor. Conductivity measurements were performed by using ac complex impedance analysis and dc experiments by using ion reversible electrodes. This work is pertinent to electric batteries.
