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.

“…[4][5][6] -irradiation is one of the known methods for changing the properties of polymers. [7][8][9][10][11] For example, 12 when polypropylene was exposed to a low irradiation dose (up to 200 kGy), it was possible to achieve a higher melt strength and special rheological properties. El-Shamy et al observed an increase in conductivity and improvement in the dielectric properties of polymer films after -irradiation.…”

The influence of the g-irradiation intensity of commercial LDPE and HDPE granules (Kazanorgsintez PJSC, Kazan, Tatarstan, Russia) on their rheological and morphological properties at irradiation doses of 5 and 10 kGy was studied. Experiments in the oscillation mode revealed an increase in the dynamic moduli values with the increase of radiation dose compared to the initial samples. At the same g-irradiation doses, HDPE samples compared to LDPE showed the greatest changes in rheological properties, while the zero shear viscosity of HDPE increased by order of magnitude compared to the initial one at the irradiation dose of 10 kGy. Morphology analysis of supramolecular structures revealed an increase in cobweb-type structures for the irradiated sample in comparison with the initial one, which may indicate the formation of branched structures under g-irradiation.
