Abstract

We report on the effect of addition of low molecular weight $(M_w =400)$ PEG on protonic conduction of the solid polymer electrolyte $(PEG)_{100} NH_4 ClO_4$. We study the changes in the temperature dependence of conductivity as a function of the amount of the added plasticizer. NMR lineshape studies indicate a reduction in the relative fraction of crystalline regions on addition of the plasticizer.We show that the plasticizer reduces both the $T_g$ and crystallinity of the samples, thus increasing the conductivity
