利用十八胺改性的酞菁绿G作为绿色显示颗粒, span80为电荷控制剂, 四氯乙烯为分散介质, 油溶黄为背景色, 制备稳定的电泳液, 采用界面聚合法制备出电子墨水微胶囊。研究了改性后的酞菁绿G 颗粒在电泳液中分散性和颗粒大小分布, 通过SEM照片证明, 当十八胺的质量分数为4%时, 酞青绿G在四氯乙烯下分散效果最好。对电泳液进行微胶囊化处理后, 在E=50 V/mm电场下, 微胶囊中的颗粒可以进行可逆运动。

Electronic ink microcapsules were prepared by the method of interfacial polymerization, stable solution of electrophoresis were produced by modified phthalocyanine green G as the green particles, span80 for the charge control agent, oil-soluble yellow for background color, PCE as a dispersion medium. Dispensability and particle size distribution of modified phthalocyanine green G in the electrophoresis medium were studied. SEM photograph is proved that when the octadecylamine mass fraction were 4%, dispersing effect of phthalocyanine green G in the PCE were the best. When E=50 V/mm, the particles in the microcapsules would be moved after the microencapsulation process is performed on the electrophoresis liquid.
