Abstract

Poly (o-toluidine) (POT) was prepared by chemical oxidation method doped with p-toluene sulphonic (p-TSA) acid in the presence of ammonium persulphate (APS) as an oxidizing agent. Polymer synthesis was optimized for different dopant–to-monomer ratios for better conductivity results. The polymer was characterized by Fourier–transform infrared (FTIR) and ultra violet-visible absorption spectroscopy (UV-Vis). Crystallinity of the sample was examined by X-ray diffraction (XRD). Temperature dependence of conductivity was studied in the temperature range 300–430 K. The conductivity was found to show an increase of ~four orders with the rise in temp. The measured conductivity versus temperature data was fitted with Arrhenius model, Mott’s variable range hopping (VRH) model in order to investigate the charge transport mechanism in the higher temperature range.
