Abstract
- Abstract: In this study, the high-intensity ultrasound was applied in the preparation of chiral polyurethane/CdS–SiO2 nanocomposites. The polyurethane/CdS–SiO2 nanocomposites were analyzed by powder X-ray diffraction, thermogravimetric analysis (TGA), TEM and SEM. The results indicated that the heat stability of the nanocomposites was improved in the presence of CdS–SiO2 core-shell nanoparticles. The infrared emissivity (8–14μm) study revealed that the nanocomposites possessed much lower infrared values compared with those of the neat polymers and nanoparticles, respectively. A possible mechanism of ultrasonic induced composite reaction was proposed based on the experimental results. [Copyright &y& Elsevier]
