摘要 采用通用聚苯乙烯(GPPS)制备了四氧化锇微胶囊。采用溶剂挥发法,分析了反应体系中溶剂、温度、分散剂等各条件对实验结果的影响,并以此进行了初步筛选。同时,为了精确地得到四氧化锇的包封率,对所制备的微胶囊包封率的检测方法进行了研究。 Preparation of microencapsulated osmium tetraoxide from GPPS was reported, and effect of solvent, temperature and dispcrsant was analyzed. Encapsulation efficiency of OsO4 in microcapsule was also studied.
