Abstract: (1736 Views)
In this study, size-tunable CdS/ZnS- polymer nanocomposite materials were successfully prepared using SILAR method. Field Emission Scanning electron microscopy (FE-SEM), Atomic Force Microscopy (AFM) and UV-Visible absorption techniques was used for morphological, surface roughness, structural and optical properties of the prepared nanocomposite materials. The confinement of electrons and holes have observed in semiconductor nanostructured materials in lower cycles of SILAR. The results of the analysis show that with increasing the number of cycles, the nanoparticle size increase, and the absorption peak of the nanostructures shifts towards higher wavelengths and consequently the energy gap decrease. Wettability measurement of CdS/ZnS- polymer nanocomposite materials was investigated by contact angle measurement of water drop on the surface. Wettability measurement of ZnS-scotch tape nanocomposite materials was investigated by contact angle measurement of water drop on the surface, and results show that with increasing of the number of cycles, the contact angle increase and the surface wettability decrease.
