采用高速均质辅助悬浮聚合法制备了粒径可控的纳米颜料-聚(苯乙烯-丙烯酸丁酯-共甲基丙烯酸)复合粒子。该复合材料具有作为高分辨率打印调色剂的潜在应用。将一种单分散、均匀球形的纳米复合蓝色颜料用于制备复合粒子。考察了搅拌速度、颜料浓度、阴离子表面活性剂浓度对复合粒子性能的影响。搅拌速度是控制颗粒大小的重要因素。所制备的复合粒子的几何平均直径在4.4~7.4μm之间，几何标准偏差在1.23~1.33之间。液滴形成过程中的高速均质有助于减小所制备的复合颗粒的尺寸。此外，合适的表面活性剂浓度对粒子的形貌有显著的影响。然而，纳米粒子的浓度并没有显著改变粒子的形态和大小。#2008威利期刊公司《应用理工学院学报》，2008
Composite particles of nanoblue pigment-poly(styrene-co-n-butyl acrylate-co-methacrylic acid) of controllable size were successfully prepared using high-speed homogenization-assisted suspension polymerization. This composite has potential application as a toner for high-resolution printing. A nanosized hybrid blue pigment, with a monodispersed and uniform spherical shape, was employed for the production of composite particles. The effects of agitation speed, pigment concentration, and anionic surfactant concentration on the properties of the prepared composite particles were investigated. Agitation speed plays an important role in controlling particle size. The prepared composite particles have geometric mean diameters in the range of 4.4–7.4 μm with the geometric standard deviation ranging from 1.23 to 1.33. High-speed homogenization during droplet formation is useful for a reduction in the size of the prepared composite particles. In addition, the appropriate surfactant concentration has a significant effect on the particles' morphology. However, the concentration of the nanopigment did not significantly change either particle morphology or particle size. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
