Dielectric studies of Phenylenediamine doped with organic acids

The polymer of aniline and its derivatives is one of the most widely researched electrically conductive polymers. Phenylenediamine doped with different concentrations of organic acids which act as dopant were prepared by chemical oxidation method. In this paper we have reported that as the concentration of dopant increases, ε' and ε” increases with temperature, may be attributable to free charge build up at the interface between the sample and the electrode (space-charge polarization).
