微胶囊技术是一种用成膜材料把固体或液体包覆成微小粒子的技术,并在很多领域得到了应用。传统的微胶囊制备方法从原理上大致分为化学法、物理法和物理化学法三大类。化学法制备微胶囊机理明确,具有影响因素多、成囊性能可控性强等特点。主要介绍了化学法制备微胶囊的原理、方法及过程控制。 Microcapsule technology is a film-forming material coated with solid or liquid into tiny particles, and has been applied in many fields. The traditional preparation method of microcapsules can be broadly divided into three categories: chemical method, physical method and physicochemical method. The microcapsules prepared by chemical method have clear mechanism, many influencing factors, strong controllability of encapsulation properties and so on. The principle, method and process control of preparing microcapsules by chemical method are introduced.
