Polyurethane nanoparticles were synthesized by using condensation miniemulsion polymerization. The miniemulsion technique was employed to produce nanoparticle in range 50 to 500 nm in diameter. 1,12-Dodecanediol and isophoronediisocyanate were polymerized in water base in the present of titanium dioxide (TiO 2 ) from 1wt%-10wt%. The encapsulated-TiO 2 /Pu hybrids nanoparticles were obtained. The mechanical properties, morphology, crystal structure and photocatalytic activity of TiO 2 /Pu hybrids were investigated. The diameter of the hybrid particles were measured using dynamic light scattering. The results show that the hydrodynamic diameter of TiO 2 /Pu hybrids were in range 164nm-219nm. The morphology of TiO 2 /Pu hybrids were observed byscanning electron microscope. The SEM micrograph presented the well-defined structure. The crystal structures were analyzed by XRD. The photoactivity of TiO 2 /Pu hybrids-coated on nonwoven fabric presented the colorless of methylene blue solution.
