Abstract: In the current study, we investigated the dielectric and optical properties of composite consist of a mixture of (PVA, PVP and PEG) with various quantities of (ZnO) nanoparticles. Optical measurement shows that polymeric blend nanocomposites based on PVA-PVP-PEG films have high absorption with different fractions of zinc oxide nanoparticles. The optical energy gaps were allowed direct transition type which decreases with film fractions increasing, i.e., it decreases from 2.9-1.5 eV with different fractions (0-4) of the zinc oxide. The dielectric behavior of composites consists of a mixture of (PVA, PVP and PEG) with various quantities of (ZnO) nanoparticles films has been scrutinized. It appears from the results that the dopant composition has large efficacy on the values of dielectric properties.
