Abstract
To study the effect of dopant type and dopant concentration on the properties of Polyaniline, a transition metal acid and an organic sulphonic acid were selected. Polyaniline with three different dopant concentrations (0.01 M, 0.05 M and 0.1 M) of each acid were prepared by chemical oxidative polymerisation using Ammonium persulphate as oxidant at 0 °C–5 °C. The morphology of the samples obtained was characterized by Field Emission Scanning Electron Microscopy (FESEM), structures were analyzed using Fourier Transform Infrared Spectroscopy (FTIR), optical properties by UV-visible spectroscopy and Photoluminescence spectroscopy. Dielectric property measurements reveal that organic sulphonic acid doped polyaniline exhibited high value of conductivity and dielectric constant than transition metal acid doped polyaniline. The samples with higher values of conductivity were selected for photocatalytic degradation study of Methylene blue under visible light irradiation. The higher degradation rate of 70.59% obtained from photocatalytic activity measurements reveals that organic sulphonic acid doped polyaniline is a better photocatalyst than transition metal acid doped one.
