中文摘要：

十八胺改性的酞菁绿G和经过改性的TiO2作为显示颗粒配制电泳液,使用明胶-阿拉伯树胶复合凝聚法制备了双色互变的电子墨水微胶囊。通过电镜照片证明,改性以后的酞菁绿G颗粒粒径变小,而且它们在四氯乙烯中的分散性能良好。对电泳液进行微胶囊化处理,电泳颗粒在微胶囊中均匀分散,调节搅拌速度以及SDS等条件,获得了表面光滑,大小均一且无粘连的电子墨水微胶囊。在E=20V/μm电场作用下,电子墨水微胶囊实现了双色互变,微胶囊中的电泳颗粒具有良好的电场响应特性。

英文摘要：

The electronic ink microcapsules containing modified phthalocyanine green G and TiO2 particles were dispersed in tetrachloroethylene（TCE）and prepared by complex coacervation with Gelatin-Gum acacia as wall materials.The size distribution of the unmodified and modified Phthalocyanine Green G was studied,the dispersing of the modified particles is better than the unmodified.The factors that affected the morphology of the electronic ink microcapsules were also discussed,and the response behavior of electronic ink microcapsules under the DC electric field was also studied.The results showed that the modified Phthalocyanine Green G and TiO2 nanoparticles have good dispersion behavior and reversibility under the electric field.
