Application of nano cerium oxide in polymer
Nano-ceria improves ultraviolet aging resistance of polymer. The 4f electronic structure of nano-CeO2 is very sensitive to light absorption, and the absorption band is mostly in the ultraviolet region (200-400nm), which has no characteristic absorption to visible light and good transmittance. Ord...Read more -
