Herein, rod-like shape of Ag2WO4 was synthesized using the co-precipitation approach. These rods were mixed with PVC using the solution casting process to create a PVC/Ag2WO4 nanocomposite film. The effect of exposing the PVC/Ag2WO4 nanocomposite film to varying doses of the electron beam (E-beam) irradiation (0, 25, 50, and 100) kGy on its structural, optical, thermal, electric modulus, complex impedance, and dielectric properties was investigated. XRD results showed that Ag2WO4 has mixed phases. The optical properties have been addressed. The thermal evaluations were performed at three distinct heating rates: 6, 8, and 10 °C/min. In the same context, the thermal activation energy (Ea) of the unirradiated PVC/Ag2WO4 nanocomposite films increased from 12.89 to 31.17 kJ/mol with the increase in E-beam irradiation doses. As a result, E-beam irradiation reduces the values of the real (ɛ′) and imaginary (ε″) components of PVC/Ag2WO4 nanocomposite films. The electric modulus analyses showed that the magnitude of the grain capacitance increased as the E-beam doses increased, while the magnitude of the grain boundary capacitance exhibited a decreasing trend. Meanwhile, a progressive reduction in the diameter of the two semicircular arcs for complex impedance analyses was observed as the doses of E-beam irradiation increase.
