以明胶-阿拉伯树胶为壁材,Span80为稳定剂,四氯乙烯为分散介质,聚甲基丙烯酸甲酯(PMMA)表面改性的TiO2为显示颗粒,采用复凝聚法制备了红白显示电子墨水微胶囊,研究了SDS对所制备电子墨水微胶囊的影响,并将微胶囊涂覆在ITO玻璃上,制成电子墨水显示原型器件。在直流电场驱动下,电子墨水显示原型器件实现了文字显示。
The electronic ink microcapsules containing TiO2 coated with PMMA particles homodispersed in TCE (tetrachloroethylene) were prepared by the complex coacervation, which shell is gelatin-gum acacia and surfactant is Span 80, and studied influence of the SDS on preparation of microcapsule. Electronic ink display prototype was prepared by coating electrophoretic ink microcapsules on ITO substrate.
