Abstract
This paper describes a novel polymer nanocomposite films with UV-shielding property, the novel films retain high visible light transmittance while shielding ultraviolet in all wavelengths. Firstly, microspheres with sizes ranging from 80Â nm to 300Â nm were prepared based on the hydrogen-bonding interaction of pyridine-terminated poly (aryl ether ketone) (Py-PAEK) and CdTe Nanocrystals and the packing of the rigid “grafts” (Py-PAEK). Whereafter a series of flexible CdTe/polymer microspheres/sulphonic poly (ether ether ketone) (SPEEK) nanocomposite thin films were fabricated by solution casting approach. The results showed that the films exhibited excellent UV-Full-Shielding properties and highly transparent in the visible region. It also indicated that a small amount of microspheres could improve the UV-shielding capability of SPEEK. As the main solvent was water, the hazards to humans and the environment were significantly decreased.
