采用简单易控制的溶剂挥发法成功制备了聚砜材料包覆苯乙烯的自修复微胶囊,通过核磁共振氢谱1(H-NMR)、扫描电子显微镜(SEM)、元素分析仪和热重分析仪(TGA)对微胶囊的化学结构、表面形貌及其热性能进行了研究。结果表明,选择0.5%的聚乙烯醇表面活性剂、700r/min乳化转速、芯壁比2∶1时制得的微胶囊表面光滑,体积平均粒径为120μm,并且分布比较窄,微胶囊在室温下具有一定缓释性。 Self-repairing microcapsules coated with polysulfone were successfully prepared by a simple and easy-to-control solvent evaporation method. Their structures were characterized by 1H-NMR, SEM, elemental analysis and thermogravimetric analysis (TGA) to study the chemical structure, surface morphology and thermal properties of microcapsules. The results showed that the microcapsules prepared with 0.5% polyvinyl alcohol surfactant at 700r / min emulsifying speed and core-wall ratio of 2:1 had a smooth surface with a volume average particle diameter of 120μm and a narrow distribution. Room temperature has some sustained release.
