Electrophoretic titania- coated polymer nanoparticles, hollow titania nanoparticles and colored polymeric nanospheres were prepared. The charged polymeric nanospheres were manufactured by emulsifier- free emulsion polymerization of methyl methacrylate, ethylene glycol dimethacrylate, butyl acrylate, [ 2-( methacryloxy) ethyl] trimethyl ammonium chloride. TiO2 coated polymeric nanoparticles were successfully synthesized by the use of the charged polymeric nanoparticles in various reaction media. Colored polymeric nanoparticles based on the positivelycharged polymeric nanoparticles were also prepared by disperse dyeing process. The morphology and properties of the colored particles were characterized by using scanning electron microscopy ( SEM), UV= visible ( UV= Vis) and photoluminescence spectra ( PL). The electrophoretic characteristics and mobility of these colored polymeric nanoparticles were also characterized.
