CdS Nanoparticles with a Thermoresponsive Polymer: Synthesis and Properties

الملخص EN

This paper describes the synthesis of thermoresponsive colloidal nanocomposites based on CdS and poly(N-isopropylacrylamide).

The CdS nanoparticles were prepared at room temperature from cadmium chloride and sodium sulfide salts in the presence of an organic ligand, 3-mercaptopropionic acid (MPA).

The as-prepared MPA-bound CdS nanoparticles were stable for more than 30 days and exhibited good optical properties.

The effect of various ratios of MPA/Cd2+ and H2O/DMF (dimethylformamide) on the particle size of the CdS nanoparticles was investigated using UV-vis absorption measurements.

Transmission electron microscopy studies showed that the particle sizes were approximately 4 nm in diameter, which is consistent with the size obtained using UV-vis spectroscopy.

The CdS nanocomposite showed a temperature-responsive phenomenon as its temperature increased from 20 to 45°C.
