Nanostructural properties of aforementioned materials were studied by scanning electron microscope (SEM) and X-ray diffraction techniques. Williamson equation was used to estimate lattice strain in the PVP-ZnO nanocomposite. The dominated peaks in XRD spectra and Williamson- Hall diagrams were considered and the nano crystallite strain was plotted by drawing strain slopes. The obtained results showed that hybrid nanocomposites synthesized at 150ºC have lower strain and therefore higher yield strain. The SEM image indicated that nanoparticles are distributed uniformly.
