TSDC and DR Studies in PEO Complexed with Inorganic Salts

Abstract

TSDC studies have been carried out on PEO complexed with inorganic salts. The results clarify the structure of the DR spectra observed previously for these materials. In the case of the gamma relaxation region, which is associated with the amorphous phase, several new relaxations are observed in PEO complexed with the various salts. Changes in the strength of these peaks give rise to the differences observed previously in the DR spectra for these materials, not only between different salts but between different concentrations of the same salt. The results show that in the amorphous phase below the glass transition, at least, the ions occupy very well defined positions vis a vis the polymer chains. Models for the relaxation are discussed along with the influence of the ions. Polyethylene oxide.
