Abstract

Thiol-ene chemistry was exploited in droplet-based microfluidics to fabricate advanced microcapsules with tunable encapsulation, degradation, and thermal properties. In addition, by utilizing the thiol-ene photopolymerization with tunable cross-link density, we demonstrate the importance of monomer conversion on the retention of omniphilic cargo in double emulsion templated microcapsules. Furthermore, we highlight the rapid cure kinetics afforded by thiol-ene chemistry in a continuous flow photopatterning device for hemispherical microparticle production.

摘要

巯基-烯化学在基于液滴的微流控技术中得到了应用,用于制造具有可调包封、降解和热性能的先进微胶囊。此外,通过利用可调交联密度的巯基-烯光聚合反应,我们证明了单体转化率对保留双乳液模板微胶囊中双亲性货物的重要性。此外,我们强调了在连续流动光图案化设备中使用巯基-烯化学所提供的快速固化动力学,用于生产半球形微颗粒。
