Optical and Electric Properties Study of PVA and PEG Thin Films Doped with ZnO nanocomposites After Irradiate By Gamma Ray

Abstract

By using gamma ray source to irradiate the polymers thin films samples at low-exposure rate, the polymeric characteristics were studied. The solution casting method was used to prepare a variety of pure polyvinyl alcohol (PVA), polyethylene glycol (PEG) polymers, and PVA:PEG blend composite films that had been doped with varying concentrations of zinc oxide (ZnO). Using a NaI(Th) system, the extent to which produced films were affected by gamma rays emitted by the ¹³⁷Cs isotope was revealed. The results of the study showed that samples with Dc conductivity measurements demonstrate how the conductivity changes in these films depending on the concentrations of ZnO present. With the aid of obtained UV-V spectra, variance in transmittance has been investigated, and the optical band gap found in these specimens has been determined.
