Sumario:PI fine particles encapsulating a large number of TiO(2) nanoparticles (PI FPs/TiO(2) NPs) were successfully fabricated rapidly and continuously by the emulsion re-precipitation method using a multistep flow synthetic system. The fabricated material, PI FPs/TiO(2) NPs, was spherical in structure with a diameter of 214 nm, and the mean size of TiO(2) NPs was 5.2 nm. Line scan elemental analysis with SEM-EDX showed that the TiO(2) NPs were disproportionately embedded near the surface of the PI FPs. UV-vis transmission spectra revealed high UV shielding efficiency of the PI FPs/TiO(2) NPs as the NPs are located near the surface.
