Study of Optical Properties for (PVA-PEG-ZnO) Nanocomposites

Bahaa H. Rubee | Sara Abd AlHussien

Abstract: The aim of this paper, study the effect of zinc oxide on optical properties of (PVA-PEG-ZnO) nanocomposites. The zinc oxide nanoparticle was added to the polymers maxture (polyvinyl alcohol 88wt. % and Polyethylene glycol 12wt. %) with different weight percentages are (0, 2, 4, 6) wt. %. . The optical properties were measured in the wavelength range (200-800) nm. The results show that the absorbance (A), absorption coefficient (), extinction coefficient (k), refractive index (n) and real and imaginary dielectric constants (1 and 2) of (PVA-PEG) blend are increasing with the increase of the weight percentages of zinc oxide nanoparticle. The energy gap (Eg) of (PVAPEG-ZnO) nanocomposites is decreased with the increase of the zinc oxide nanaparticles concentrations.
