Optical properties for prepared polyvinyl alcohol polyaniline ZnO nanocomposites

الملخص EN

The optical energy gap and optical constants such as the reflective index, dielectric constant have been evaluated due to The optical transmission and UV-VIS absorption spectra have been recorded in the wavelength (200 - 1100 nm) for PVA/PANI polymer blends and PVA/PANI/ZnO nanocomposites with different concentrations of ZnO (0.02, 0.05, 0.07, 0.1and 0.2) wt %.

The results indicate that the materials have allowed direct transition.

The reflection index and dielectric constant are increase with wavelength.
