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=50V/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 i% ,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.
