• Variation in viscosity and ion conductivity of a polymer–salt complex exposed to gamma irradiation

We study changes in microstructure and resulting changes in the properties of PEO($1 − x$)–NH4 ClO4 (𝑥) samples where $x = 0.18$, when irradiated with gamma doses varying up to 50 kGy. Viscosities of aqueous solutions of the irradiated samples give an idea of the change in molecular weight and show correlation with ion conductivity. On the whole, there is a chain scission on irradiation, though there is evidence of some cross-linking at higher doses. The ion conductivity shows a strong increase for an irradiation of 35 kGy. DSC studies indicate a decrease in crystallinity with gamma dose.
