摘　　要： 以汉沙黄10G为原料,以超分散剂和协同分散剂为改性剂制备了颜料电泳粒子。研究了改性汉沙黄10G在电泳介质中的分散性、粒径分布和电泳淌度,通过FTIR和SEM对超分散剂改性的汉沙黄10G进行了结构和形貌的表征。并以包含改性汉沙黄10G的分散液为核材料,通过复凝聚法制备了电子墨水微胶囊,研究发现改性汉沙黄10G在微胶囊内具有可逆的电场响应行为。 Pigment electrophoretic particles were prepared with Hansa yellow 10G as materials,hyperdis-persant and assistant-dispersant as modifier.Dispersibility,particle size distribution and electrophoretic mobility of modified Hansa yellow 10G in the electrophoretic medium were studied.The Hansa yellow 10G particles modified with hyperdispersant were characterized by FTIR and SEM.E-Ink containing dispersion liquids of modified Hansa yellow 10G was prepared by coacervation.Experiments revealed that Hansa yellow 10G particles modified with hyperdispersant had reversible electric response in the microcapsules.
