The gamma (γ) induced modifications in the synthesized Pani-Ag/PVA nanocomposite (NCP) thermal and optical characteristics have been depicted. The induced effect was investigated applying X-ray diffraction, differential scanning calorimetry, and UV-spectroscopy. Further, the color intensity (ΔE) of the irradiated NCP and blank has been estimated. The γ radiation decreases the optical band gap value from 2.65 to 1.54 eV owing to the randomly amorphous dominance in the irradiated NCP. Moreover, γ radiation induced noticeable defects generation, splitting the crystals, leading to depressed melting temperature.
