Precise Syntheses of High Performance Color Electronic Inks Applicable to Full-Color Electronic Paper

近来，要求低成本、低重量、良好的柔性和低功耗的电子相纸在信息显示器中的应用引起了极大的兴趣。 显示器的制造可以以几种方式实现，例如通过使用双折射液晶、扭曲的白-黑球、具有液晶的移动的精细颗粒、面内电泳颗粒或微囊化电泳颗粒。 在这些不同的材料中，微囊化电泳显示器（EPD）提供了较低制造成本的优点。本研究以低介电常数介质Isopar和硅油为分散聚合介质，研究了新型高性能白色和彩色微球的制备和粒径控制。 我们还研究了新的制备方法的稳定的分散体的二氧化钛微粒包覆聚合物和带电性控制的颗粒在碳氢化合物介质中。

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.
