Pyrene was mixed with polystyrene (PS) in different molar concentrations in the range 0.2-12 mol.... more Pyrene was mixed with polystyrene (PS) in different molar concentrations in the range 0.2-12 mol.% and thermally stimulated discharge (TSD) current spectra of the doped PS films were studied for various dopant concentrations, polarizing fields and forming temperatures. Unpolarized films were observed to give a peak at 95 °C. The TSD current peak in the main relaxation region of PS shifts to the lower temperature side of the spectrum with increasing concentration of the dopant. The strong dependence of space charge polarization on the dopant concentration and the forming temperature IS assigned to an increase in the conductivity of the polymer.
