The cationic polyurethane/CeO₂ nanocomposite dispersion has been synthesized 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 CeO₂. TEM micrograph shows that CeO₂ nano-particles are uniformly dispersed in polyurethane. Polyurethane/CeO₂ nanocomposite has high absorption at the region lower 350 nm.
