The blend specimens of [PVA(47)-PEO(47)-EC(6)-(LiCF3SO3)x] system are prepared for x = 3 to 11 wt % using solution cast technique. Portions of these blend films are exposed to swift heavy O7+ ion radiations. Changes taking place in thermal, electrical and relaxation properties at various LiCF3SO3 salt concentrations of all the blend specimens prior and after irradiation are thoroughly investigated. Relaxation time τ and Kohlrausch-William-Watt's exponent β which throw light on the relaxation dynamics of the blend samples are calculated using modulus formalism. For both, prior as well as after irradiation, all these properties are found to be optimum at 9 wt% of salt concentration. However, irradiation has led to a significant enhancement in these properties of the blends at all salt concentrations. Scaling of modulus is carried out to analyse time-composition superposition principle. Relaxation dynamics is observed to be independent of salt concentration in cases of both, pristine and irradiated blends.

Abstract


The blend specimens of [PVA(47)-PEO(47)-EC(6)-(LiCF3SO3)x] system are prepared for x = 3 to 11 wt % using solution cast technique. Portions of these blend films are exposed to swift heavy O7+ ion radiations. Changes taking place in thermal, electrical and relaxation properties at various LiCF3SO3 salt concentrations of all the blend specimens prior and after irradiation are thoroughly investigated. Relaxation time τ and Kohlrausch-William-Watt's exponent β which throw light on the relaxation dynamics of the blend samples are calculated using modulus formalism. For both, prior as well as after irradiation, all these properties are found to be optimum at 9 wt% of salt concentration. However, irradiation has led to a significant enhancement in these properties of the blends at all salt concentrations. Scaling of modulus is carried out to analyse time-composition superposition principle. Relaxation dynamics is observed to be independent of salt concentration in cases of both, pristine and irradiated blends.
