摘　　要：　电泳显示、LCD等信息显示技术,应用于电子纸产品,存在性能不稳、产品寿命短等问题。本文综述了复凝聚、原位聚合等微胶囊合成方法及其改进技术,包括使用阻聚剂提高胶囊平滑度、加入抗冲击剂改善胶囊分散状态以及无机颜料、有机颜料和纳米SiO2等电泳颗粒的微胶囊改性技术,展示了电泳墨水微胶囊技术的新进展。微胶囊技术应用于电泳显示、LCD以及双色球和磁性电子纸等,改善了电子纸显示器性能,促进了电子纸及其应用技术产业化发展。Many display technologies applied in electronic paper are disturbed by the shortage of instability and short life-span. Based on the latest reports and our experiments, the microcapsule process and its improvements are described in this paper. Such as the in-situ polymerization, the agglomeration polymerization, the polish up of microcapsule surface with polymerization inhibitor and the capsule dispersion improved by couple-preventing agents. The encapsulating of electrophoretic particles includes organic, inorganic and nano particles. The properties of electronic paper that based on the elctrophoretic display, LCD, gyricon and magnetic display were improved effectively by the application of microcapsule. The industrialization of electronic paper was promoted by the microcapsule technology greatly.
