    • Provided is a method for preparing uniformly sized and shaped, mono-dispersed microcapsules using miniemulsion polymerization. In microcapsules prepared by the method, a liquid or solid core encapsulated by a polymer shell has 10 to 80% by volume of the microcapsules. Since miniemulsion particles produced at an early stage of the method are stable, an organic material which is well dissolved in monomer particles and has a higher interfacial tension with water, relative to the polymer shell, can be uniformly positioned in polymer particles. Furthermore, when a crosslinking agent is added during the polymerization, single-core microcapsules can be obtained. In addition, use of an oil-soluble initiator can prevent formation of secondary particles and addition of a secondary initiator during the polymerization can increase the yield of the uniformly sized and shaped microcapsules.
    • 提供了使用细乳液聚合制备均匀尺寸且成形的单分散微胶囊的方法。 在通过该方法制备的微胶囊中,由聚合物壳包封的液体或固体核具有10至80体积%的微胶囊。 由于在该方法的早期阶段产生的微乳液颗粒是稳定的,所以相对于聚合物壳,良好溶解在单体颗粒中并且与水具有较高界面张力的有机材料可以均匀地定位在聚合物颗粒中。 此外,当在聚合过程中加入交联剂时,可以获得单核微胶囊。 此外,使用油溶性引发剂可以防止二次粒子的形成,并且在聚合过程中添加二次引发剂可以提高均匀尺寸和形状的微胶囊的产率。
