摘要
以十八胺改性的酞菁绿G为显示颗粒,Span80为电荷控制剂,四氯乙烯为分散介质,油溶黄为背景色,制备了分散稳定的电泳液。以明胶阿拉伯树胶为壁材,采用复合凝聚法制备了电子墨水微胶囊。实验表明,改性的酞菁绿G在四氯乙烯中具有良好的分散性;在E=10V/μm,实现了电泳液电泳显示,且黄绿双色互变清晰、明显,实现了相互遮盖;在平行电极显示中,当加E=0.5V/μm时,酞菁绿G颗粒在电子墨水微胶囊中实现了快速移动,表现了良好的电场响应。
The stably dispersed electrophoretic fluid contains octadecylamine-modified phthalocyanine green G which is used as electrophoretic display particles,Span80 as charge control agent,tetrachloroethylene（TCE） as dispersion medium,and oil-soluble yellow as background.The electronic ink microcapsules are prepared by complex coacervation,and the shell is made from gelatin and gum arabic.Parallel electrodes display shows that the mobility of phthalocyanine green G in the electronic ink microcapsules and the conversion between yellow and green is good.The results show that the modified phthalocyanine green G particles have good dispersion and reversibility under electric field.
