微胶囊由于优良的性能而受到研究者的广泛关注,常用的制备方法有界面聚合法和原位聚合法等。其中原位聚合法是一种重要的微胶囊制备方法,具有成本低、适合工业化生产等优点。主要介绍了原位聚合法制备微胶囊的原理,以及制备过程中壁材原料、乳化剂、乳化速度等相关因素对制备效果的影响,重点阐述了近年来原位聚合法在制备相变材料微胶囊、阻燃剂微胶囊和自修复材料微胶囊等方面的研究现状。最后指出了原位聚合法在制备微胶囊研究中存在的问题,也对该领域未来的研究方向提出了建议。
Microcapsules have attracted considerable attention because of its excellent properties.Interfacial polymerization and in-situ polymerization methods are widely used for the preparation of microcapsules.In-situ polymerization is one of the most important methods to prepare microcapsules with the advantages of low cost and suitable for industrial production.The principle of in-situ polymerization,and its influence factors,such as raw material of the wall,emulsifier,stirring rate and so on were introduced.In addition,the application of in-situ polymerization in phase change microcapsule,flame retardant microcapsule and self healing microcapsule were summarized.Finally,the existing problems of method were pointed out and the potential development directions were proposed.
