Abstract: PmAP and PmAP/WO3 composite are synthesized by chemical oxidation polymerization process. Synthesized materials are investigated by UV Visible, SEM and cyclic-voltagram (CV) techniques. SEM study of as prepared materials is indicated formation of different sized crystals (small and aggregated). In UV Visible spectra analyses, both transitioned (i.e., π-π* transition and charge transfer of polaron band) are observed. Tauc expression is used to estimate optical band gap. Estimated optical band gap is to be 3.09 eV. Oxidation-reduction potential profile is detected in cyclic voltammetry (CV) analyses of PmAP and PmAP/WO3 composite.
