Abstract In the current work, the effect of Cd0.9Co0.1S nanostructures concentration as fillers on the structure and optical properties of single-walled carbon nanotubes/polyvinyl alcohol (SWCNTs/PVA) blend has been explored. Different concentrations of Cd0.9Co0.1S nanostructures filled SWCNTs/PVA nanocomposites were prepared via casting technique. FT-IR spectroscopy was used to examine the structures’ variation of the prepared samples. XRD technique was applied to explore the structural properties. XRD analysis reveals that the prepared filler possesses a nanostructured nature with a simple cubic structure. While the XRD measurements of all filled SWCNTs/PVA nanocomposites exhibit amorphous characters. The optical properties were explored using a UV-Vis-NIR spectrophotometer. The obtained direct bandgap of the filled samples decreases from 5.34 to 4.92 eV as filler’s concentration is increased from 0 to 10 wt%. Enhancement of the optical parameters (refractive index, dielectric permittivity and optical conductivity) of SWCNTs/PVA blend could be achieved via Cd0.9Co0.1S nanostructures filling. The prepared Cd0.9Co0.1S filled SWCNTs/PVA nanocomposites could play a great role in optoelectronic and energy storage applications.
