Abstract :

 The effects of gamma radiations on the properties of PVA(1–x)PSx (x = 0.0, 0.25,0.50, 0.75 and 1.0) polymer blend films have been investicated. The changes in the properties of polymer films induced by gamma–irradiation are investigated by using X–ray diffraction, AC electrical conductivity and impedance spectroscopic techniques. The maximum AC conductivity was found to be 1.054×10−6 S cm−1 at room temperature for PVA polymer film irradiated to 1.5 kGy dose. The conductivity increases from 1.054×10−6 S cm−1 to 12.582×10−6 S cm−1 when the temperature is raised to 135 ºC. The bulk resistance (Rb) has been calculated from the Cole–Cole spectroscopic plot. The magnitude of the bulk resistance decreases with an increase in temperature from 30 ºC to 110 ºC also decreases with increasing γ –ray irradiation dosage
