Conducting poly(o-toluidine) (PoT) was synthesized from a derivative of aniline (o-toluidine) monomer by chemical oxidative polymerization method. After polymerization, the polymer prepared was then blended with Poly Vinyl Chloride (PVC) to achieve films. FTIR and UV-Visible studies were carried out to get their optical information. The blends were irradiated by Swift Heavy Ion (SHI) beam of 60 MeV C5+ ions with different fluences. Post Irradiation FTIR and UV-Visible spectroscopy were carried out on these films, which revealed changes in the band gap with irradiation. There are also changes in the functional groups, which are confirmed by FTIR spectra. Optical band gap is found to decrease at all fluences and increased with increase in fluence.
