In this study, we prepared monosultap microcapsules in an inverse emulsion through interfacial polymerization for the first time. The microcapsules are spherical pellets with intact and smooth shell and have a narrow particle size distribution with an average size of about 2.35 μm. More importantly, our microcapsules have excellent thermal stability with a starting decomposition temperature of 233.1 °C, high encapsulation efficiency of 81.9% as well as long‐term slow release of monosultap under different conditions. In addition, the shell of the microcapsules can degrade completely in the natural condition, avoiding the pollution to the environment. It can be believed that our microcapsules will show good service performance if employed in agricultural industry. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48594.

通过界面聚合制备反相乳液中的单磺基聚氨酯微胶囊

在本研究中,我们首次通过界面聚合在反相乳液中制备了单ultapultap微胶囊。微胶囊是具有完整且光滑的壳的球形粒料,并且具有窄的粒度分布,平均粒度为约2.35μm。更重要的是,我们的微胶囊具有出色的热稳定性,起始分解温度为233.1°C,包封效率高达81.9%,并且在不同条件下可以长期缓慢释放单核舒普特。另外,微胶囊的壳在自然条件下可以完全降解,避免了对环境的污染。可以相信,如果用于农业,我们的微胶囊将显示出良好的服务性能。分级为4 +©2019 Wiley Periodicals,Inc.J.Appl。Polym。科学 2020年137,48594。
