摘要：
The study investigates the impact of gamma radiation on the optical, structural and electrical properties of Polyaniline (PANI) and Polyvinyl Chloride (PVC) composites having 30% PANI concentration exposed to varying doses of gamma radiation (25-100 kGy). The multiple peaks in PL spectroscopy and shift in the UV-Vis absorption band towards lower wavelengths indicate chain scissoring due to gamma radiation. The increase in amorphous behavior of the composites with increasing irradiation doses is confirmed by an increase in Urbach's energy and XRD spectra. FTIR analysis indicates chain scissoring and free radical production in PVC chains. SEM images revealed surface modification as is evident from the formation of clusters and rods.
