文摘The cationic polyurethane/CeO 2 nanocomposite dispersion has been synthesiz ed by adding ceria organosol to pre-polymer of polyurethane and then adding neutralization reagent and water to give an emulsion. FTIR analysis shows blue shift of the absorpsion band of CeO 2 . TEM micrograph shows that CeO 2 nano- particles ar e uniformly dispersed in polyurethane. Polyurethane/CeO 2 nanocomposite has high absorption at the region lower 350 nm.
