초록
Titanium dioxide (TiO2) nanoparticles were encapsulated with polystyrene (PS)-based copolymeric materials for an electrophoretic display application. This coating process was performed in order to improve the dispersion stability of electrophoretic pigment particles in a dielectric medium and to reduce the density mismatch between TiO2 and the dielectric medium. The characteristics of polymer-coated TiO2 nanoparticles of the density, chemical structure, particle size, shape, and morphology, were examined respectively by FT-IR, thermogravimetric analysis, particle size analysis, and SEM. Additionally, the electrophoretic mobility of the fabricated nanoparticles with a charge control agent was determined by measurements of the zeta potential.
