    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.
