有机颜料酞菁蓝微胶囊的原位微悬浮法制备及其表征
DOI: 10.3724/SP.J.1105.2011.10008, PP. 145-150
Keywords: 有机颜料,微胶囊,原位微悬浮聚合,结构形态
Abstract:
通过简单的超声分散及强力剪切将滤饼中的有机颜料颗粒以初级粒子形式均匀稳定地分散到单体分散液和微悬浮液中的单体小液滴内，经有机颜料单体分散液的预聚处理和原位微悬浮聚合制备得到一系列具有高颜料包裹率和窄粒径分布特点的微米级聚合物胶粒.实验观察和粒径分析DLS证明，预聚处理可明显提高微悬浮体系中单体液滴相的黏度，因而可有效改善微悬浮体系的聚合稳定性，并降低聚合物胶粒的粒径及其分布；通过协同调节体系分散剂磷酸三钙（TCP）用量和搅拌速率可在保持聚合胶粒较窄分布的同时，在较大范围内实现对胶粒大小的有效调控.光学显微镜（OM）和透射电镜（TEM）观察证明，大量铜酞菁小颗粒已完全被均匀稳定地包裹在具有规整球状特征的聚合物胶粒内，聚合胶粒均具有典型的“石榴状”微胶囊结构.
