| Research Abstract |
Electronic rewritable papers have recently attracted a great deal of interest for use in information displays, requiring low cost, low weight, good flexibility, and low power consumption. The fabrication of the displays can be achieved in several ways, such as by using cholesteric liquid crystals, twisting white-black balls, mobile fine particles with liquid crystals, in-plane electrophoretic particles, or micro-encapsulated electrophoretic particles. Among these different materials, microencapsulated electrophoretic displays (EPDs) offer an advantage of lower manufacturing cost. In this study, we have studied the preparation and particle size control of novel high performance white and color microspheres by dispersion polymerization in low dielectric constant media, such as Isopar and silicone oils. We also study new preparation methods of stable dispersions of TiO2 fine particles encapsulated with polymers and the chargeability control of the particles in the hydrocarbon media.
