Preparation of Spheric and Hollow TiO2 Electrophoretic Nanoparticles


Article Preview

The inorganic electrophoretic particles easily sedimentate and are not preferably dispersed in medium because their density is relatively big. Spheric and hollow TiOB2B particles were prepared against the core-shell polymer latex particles via a simple wet-chemistry route, using Ti(OBu)B4B as a precursor. The particles¢ morphology was observed by atom force microscopy (AFM) images, scanning electron microscope (SEM) and transmission electron microscopy (TEM). The products were characterized by X-ray Diffraction (XRD) and TEM. TEM showed spheric and hollow particles with a diameter around 290 nm. The density (in the atmospheric pressure, 20°C) of TiOB2 Bwas 2.21 g∙mLP-1P. Results showed that hollow framework could reduce the density of particles. The Zeta potentials were determined by micro-electrophoresis apparatus. TiOB2B particles had good electrophoretic property, and the Zeta potential was 5.25 mV.
