Triple emulsion drops with an ultrathin water layer are developed to achieve high encapsulation efficiency of hydrophobic cargo in a hydrophobic polymeric shell, directly dispersed in water. Furthermore, enhanced retention of volatile hydrophobic cargo is achieved by forming a hydrogel network within this water layer that serves as a physical barrier.
研制了具有超薄水层的三重乳液液滴,以实现在疏水性聚合物壳中对疏水性货物的高包封效率,且直接分散在水中。此外,通过在该水层内形成水凝胶网络来增强挥发性疏水性货物的保留,该水凝胶网络起到物理屏障的作用。
