Synthesis and characterization of CdS nanocrystals and maleic anhydride octene-1 copolymer nanocomposite materials by the chemical in-situ technique

In the present work, in-situ chemical co-precipitation method was employed for the preparation of CdS nanocrystals in the copolymer matrix. The process has been carried out successfully and the nanocomposites have been obtained with excellent optical and structural properties. During the process it was determined that the grain size of nanoparticles depend on regulation of the reaction conditions and on the proportions of the precursors in this method. Also the results have shown that the sizes of the nanoparticles increase with the increase of temperature and this shifts revealed in measurements. Surface morphology and crystallinity have been studied by AFM and XRD techniques, respectively. The average size of nanocrystals was calculated 2-6 nm by AFM and XRD measurements. Consequently, it have been detected that elaborated CdS nanocrystals demonstrate new interesting structural and optical properties. A detailed optical property of the obtained CdS/MA-octene-1 nanocomposite material is done by characterizing UV-Vis, FT-IR and PL spectrophotometric methods.
