To realize the microcapsule-based electrophoretic displays, the individual pigment particles should be dispersed in the dielectric fluid. In this study, titanium dioxide (TiO2) nanoparticles were encapsulated with polystyrene based copolymers in order to improve the electrophoretic characteristics of modified TiO2. The chemical structure of the surface modification, morphology and the surface charge of the TiO2 particles were characterized. The particles were dispersed in a suspending fluid and then were encapsulated to form microcapsules of about 100 μm in diameter. With gelatin and gum arabic as wall materials, microcapsules were prepared through the phase separation of oppositely charged polymers. We fabricated a 2.4 inch panel of 520 X 520 array of pixels with passive matrix addressing. |
