以虫胶(CS)为基质，分别包裹三聚氰胺甲醛微胶囊(A)或纳米CaCO3稳定微胶囊(B)，两者均包埋油基活性成分，制得A-CS或B-CS复合微胶囊。对复合微胶囊的力学性能和释油特性进行了评价。复合微胶囊的机械稳定性增强，有效成分的渗漏减少了一个数量级。(C)2015年中国科学院颗粒学会和过程工程研究所。爱思唯尔出版，版权所有。
A calcium shellac (CS) matrix was used to encapsulate polymeric melamine formaldehyde microcapsules (A) or CaCO3 nanoparticles-stabilized microcapsules (B), both of which encapsulated an oil-based active ingredient, producing A-CS or B-CS composite microcapsules. The mechanical properties and oil release profiles of the composite microcapsules were evaluated. The composite microcapsules showed enhanced mechanical stability and reduced leakage of the active ingredient by one order of magnitude.
