Abstract

The effect of hydroquinone doping in poly (vinyl alcohol) thermoelectrets has been studied by the thermally stimulated depolarization [TSD] technique. The activation energy and the relaxation time have been calculated using the initial rise method. The slope of In J vs 1/T plot for PVA thermoelectrets is constant indicating a single relaxation process. On doping, the slope of the curve indicates two different values of activation energy. The temperature corresponding to the current peak is found to change with the heating rate.
