Abstract Supercritical emulsions extraction (SEE-C) technology was used to produce PMMA/diglycidyl ether of bisphenol A microcapsules acting as a health-monitoring element. A comparison between SEE-C and solvent evaporation was carried out. Best results were obtained using SEE-C: spherical microcapsules with a smooth surface and a mean size of 220 nm, with an encapsulation efficiency up to 79%, were obtained. SEE-C capsules preserve their stability for the entire time frame analyzed (30 days). Impact tests were carried out on strips of carbon fiber reinforced composites coated with an aqueous paint in which capsules were previously dispersed: dye leaking associated with capsules breaking was evidenced.

使用超临界乳液萃取将健康监测剂封装在聚甲基丙烯酸甲酯微胶囊中

摘要 采用超临界乳液萃取（SEE-C）技术生产作为健康监测元件的双酚A微胶囊PMMA/二缩水甘油醚。进行了 SEE-C 和溶剂蒸发之间的比较。使用 SEE-C 获得了最佳结果：获得了表面光滑、平均尺寸为 220 nm、封装效率高达 79% 的球形微胶囊。SEE-C 胶囊在分析的整个时间范围内（30 天）保持其稳定性。对涂有预先分散有胶囊的水性涂料的碳纤维增强复合材料条进行冲击试验：证实了与胶囊破裂相关的染料泄漏。
