Conductivity enhancement in PVA−PEO−EC−LiCF−3SO3 blends upon swift heavy O7+ ion irradiation

In the present study, the PVA−PEO−EC−LiCF−3SO3 blend system was prepared using solution cast technique. The system was prepared by taking 5 different concentrations LiCF3SO3 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 O7+ radiations of 80 MeV at a current of 1pnA at a fluence of 1×1012 ions/cm2. 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.
