Abstract
CuO/PVA-PEG nanocomposites were prepared by solvent casting method. In XRD spectra, the shifting of peak position and the absence of remaining characteristics peaks of CuO nanoparticles in CuO/PVA-PEG indicates the formation exfoliated nanocomposites. The SEM image reveals the complete dispersion of the nanofillers in polymer matrix. FTIR spectra revealed the formation of strong H-bonds between PVA and PEG during mixing. The absorption and transmission properties of the sample were studied by UV-Vis studies. Z-scan analysis confirms the presence of two-photon absorption in the sample. The synthesized polymer nanocomposite exhibits optical nonlinearity due to the excitonexciton interaction.
