Effect of CdS Nanoparticles on the optical properties of (PVA-PVP) blends.

The effect of cadmium sulfide Nanoparticles on the optical features of the polymer matrix of polyvinyl alcohol and polyvinyl pyrrolid is studied in this work. Samples of nanocomposites (PVA-PVP-CdS) using the casting process, Preparations have been made Percentages for weight cadmium sulfide nanoparticles (o,1,2,3, and 4 ) wt % the experimental outcomes indicate that absorption of the , of the coefficient of absorption, coefficient of extinction with the increasing concentrates in concentrations (CdS) of nanoparticles, refractive index of and Dielectric of constant (real, imaginary ) There is a growing rise in. the energy gap decreases as the concentration of cadmium sulfide nanoparticles increases . (FTIR) shows that the (CdS) nanoparticles (PVA-PVP-CdS) nanocomposites contribute to small vibrational molecular movement; some polymer chains have also been broken after adding (CdS) nanoparticles. Instead, several other chains were established.
