摘要/Abstract

采用悬浮聚合法合成了多孔高分子聚苯乙烯交联微球(PS)为载体, 采用“孔内析晶”策略将薄荷醇凉味剂成功地负载到PS微球孔道中, 制备了一系列负载L-薄荷醇的多孔PS微球样品. 采用热风吹扫的方式, 研究了负载薄荷醇的PS球在不同温度下的薄荷醇释放行为, 发现薄荷醇的释放过程符合双相动力学规律. 相对于机械混合的样品, 负载型PS样品释放薄荷醇的速率在较宽的温度范围内(30～80 ℃)均显示出较好的缓慢释放特点. 这种新颖的制备工艺为设计高性能负载型薄荷醇制品提供了新的思路.

In this study, cross-linked polystyrene microspheres (PS) with high porosity were synthesized via a suspension polymerization method. A series of menthol@polystyrene microsphere composites were synthesized via a novel "in-pore crystallization" strategy by employing porous PS microspheres as the carrier. The release behavior of menthol under different temperature was studied by a hot-air sweeping method, and it was found to be fitted with the law of biphase kinetics. Compared to the samples obtained via mechanically blending, the present supported composites display a controlled release of menthol in a rather broad temperature range (30～80 ℃). This kind of new preparation technology is expected to be useful for designing novel high-performance menthol-based products.

Key words: suspension polymerization, porous polystyrene, menthol, in-pore crystallization, controlled release
