The prime goal of this work is to synthesize free‐standing polyvinyl alcohol (PVA) films doped with Ag2S, CuS, Ag2S/CuS alloy, and Ag2S/CuS nanocomposites through the sol–gel route. The dependence of Ag2S content in the PVA nanocomposite films on both the real and imaginary parts of the complex permittivity and loss tangent values was examined. An enhanced dielectric constant was achieved with minimum...
