Abstract

Hollow black TiO nanoparticles were obtained via deposition of inorg. coating on the surface of hollow core-shell polymer latex with Ti(OBu)4 as precursor and subsequent calcination in ammonia gas. Hollow TiO particles were characterized by scanning electron microscope, transmission electronic microscopy, X-ray diffraction, and thermogravimetric anal. Encapsulation of TiO via dispersion polymn. was promoved by pretreating the pigments with 3-(trimethoxysilyl) Pr methacrylate, making it possible to prep. hollow TiO-polymer particles. When St (styrene) and DVB (divinylbenzene) were used as polymn. monomer, hollow TiO-polymer core-shell particles came into being via dispersion polymn., and the lipophilic degree is 28.57%. Glutin-arabic gum microcapsules contg. TiO-polymer particles electrophoretic liq. were prepd. using via complex coacervation. It was founded that hollow TiO-polymer particles had enough electrophoretic mobility after coating with polymer. [on SciFinder(R)]
