【摘要】 电子纸具有低能耗、可挠便携等优势,成为近年来的研究热点。E-ink率先将微胶囊技术产业化,Sipix的微杯技术制备成本更低、性能更优良,成为最具潜力的显示技术。全彩化、高反射率与高对比度、低电压、快响应、可挠性、低成本量产、环保等成为电子纸的前景目标。本论文着眼于采用简易设备与材料,以低成本、环保节能方式,实现高反射、低电压响应、抗蚀可挠式电子纸的构建。其主要工作和创新性如下:1.通过对具有高官能度、柔顺链结构和可对基材锚定的材料体系的选择与共混,构筑了对四氯乙烯介质抗蚀、聚酯基材上可挠、微室可用光固化材料体系。2.以无需模具的掩膜湿膜光刻法制备微室的微杯,创新地采用氟碳表面流平剂FC-500、羧基丙烯酸酯EM213、含乙二醇单元光引发剂Irgacure 2959为主的材料体系,对微杯以界面光固化实施封装,构筑了耐四氯乙烯介质的微室结构。该微室结构构建的电子纸可耐受80℃持续烘烤,110℃下对四氯乙烯密封性好,具有可自由弯曲可挠的性能,同时解决了溶剂造成的环保问题,且成本低廉。3.通过将具有酸性基团的高分子共聚物BYK110、具有颜料锚定基团的高分子量嵌段共聚体BYK161、具有氨基结构的硅烷550复配,以“一锅法”方式代替繁琐的颜料改性工序,对二氧化钛等颜料超分散,制得了电子墨,并以光化学制得修饰电极,实现了电子纸66%的高反射率、140ms/5V的低电压响应的双稳态电泳显示性能。在以上工作基础上提出一体化法构筑彩色电子纸微室的新方法设想,初步研究了材料组分的影响因素,希望为低成本构建高性能彩色电子纸提供一定的实验依据。更多还原

【Abstract】 Owing to ultra low energy-consumption, excellent flexibility, lightweight, electronic paper (E-paper) has attracted most interests recently. Although the microcapsule-type technology was first industrialized by E-ink Corporation, the microcup-type technology of Sipix Corporation seems becoming the one of the most potential display technologies due to its lower cost and better performances. Now, the full-color, high contrast, reflection, low-voltage, fast response, flexible, low-cost, and environmental protection have become the prospects of the future E-paper.This doctoral dissertation focused on the low-cost, environment-friendly and energy-saving E-paper, which was fabricated with cheap and easily available materials and equipments. The main contents of this dissertation were given as following: the chief achievements and novelties are presented in the following 3 parts:First, by choosing and blending the acrylic resin with multi-functions, flexibility, anchoring groups or segments structures, UV-curing material system has been constructed for solvent resistence, flexibility, tetrachloroethene-media microcontainer on ITO/polyester substrate.Secondly, the microcontainer of tetrachloroethene-media has been fabricated by photomask lithography instead of moulding process, followed by interfacial sealing without cosolvent, which can solve the pollution problems in low-cost way. The aforementioned sealing materials consisted of blending of fluorocarbon-base flatting agent, acrylic esters with carboxyl group and photo-initiator with glycol group, i.e., FC-500, EM213, Irgacure 2959, innovatively. The microcontainer of tetrachloroethene-media shows good properties, such as long-term thermal endurance of 80℃, good sealing appearance below 110℃, free bending and excellent flexibility. Furthermore, to obtain electronic ink, the blending of acid-containing co-polymer, block polymer of high molecular weight with anchoring group for pigment and silicon coupling agent with amido group, i.e., BYK110, BYK161, KH-550, has been applied to pigments containing titania in one-pot and dispersing way. The electronic ink can display between bi-stability states by electrophoretic, with the high reflection of 66% and responding time of 140ms by 5 voltages.The integration method to fabricate full-color E-paper was proposed on the basis of the results of research. Moreover, the related impact factors have been studied, which could become the preliminary research foundation of fabrication of full-color E-paper in a low cost and high properties way.更多还原
