Title: Conductivity enhancement in PVA−PEO−EC−LiCF−{sub 3}SO{sub 3} blends upon swift heavy O{sup 7+} ion irradiation

In the present study, the PVA−PEO−EC−LiCF−{sub 3}SO{sub 3} blend system was prepared using solution cast technique. The system was prepared by taking 5 different concentrations LiCF{sub 3}SO{sub 3} in the range of 3wt% to 11 wt%, at a fixed proportion of the rest of the constituents. These blend films had been exposed to O{sup 7+} radiations of 80 MeV at a current of 1pnA at a fluence of 1×10{sup 12} ions/cm{sup 2}. The conductivity variation of the specimens is investigated using impedance spectroscopy wherein; the conductivity enhances drastically upon irradiation at all the concentrations of salt. The thermal characteristics of the blend films are being studied using Differential Scanning Calorimetry.
