Abstract
In the present research, the synthesis and characterization of poly(arylene ether ketone) (PAEK)–cadmium sulfide (CdS) nanocomposites prepared using carboxylic-functionalized PAEK (PCA-PAEK) as the ligand in dimethylformamide solution from cadmium acetate and thiourea is reported. The resulting CdS/PCA-PAEK nanocomposites were characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, ultraviolet–visible (UV-vis) spectroscopy, and photoluminescence (PL) spectroscopy, confirming the formation of CdS quantum dots (QDs) with small particle size. The results of PL measurement showed that the nanocomposite exhibited distinct luminescence properties. Furthermore, the effects of reaction time, CdS/PCA-PAEK ratio, and Cd2+/thiourea ratio on the PL of CdS QDs were also investigated. Thus, a novel simple route was successfully developed for synthesizing nanohybrids based on QDs and high-performance polymers with incorporated carboxylic moiety.
