摘　　要：文中以聚氨酯为内层壁材、壳聚糖为外层壁材,采用原位聚合法制备包覆薰衣草精油的壳聚糖聚氨酯双层壳香味微胶囊,探讨了分散剂种类和用量的影响,测试合成的微胶囊粒径、表面形貌、留香效果。结果表明,壳聚糖聚氨酯双层壳香味微胶囊呈规则球形,囊壁致密而完整;用Tween80作为分散剂,可制得平均粒径为0.756μm,分布系数为0.623的壳聚糖聚氨酯双层壳香味微胶囊;与纯精油和聚氨酯单层壳微胶囊相比,壳聚糖聚氨酯双层壳香味微胶囊可获得较好的香味缓释效果。Chitosan and polyurethane double-shell fragrant microcapsule coated with lavender essential oil was prepared with polyurethane as inner shell material and chitosan as outer shell material by in -situ polymerization method. The effects of the types and amount of dispersants were discussed and the particle size, surface morphology and fragrance release effect of the synthesized microcapsules were tested. The results show that the Double-shell fragrant microcapsule has a regular spherical shape, and the capsule shell is compact and complete. Tween80 as a dispersant can obtain a chitosan and polyurethane double-shell fragrant microcapsule with an average particle size of 0.756 μm,distribution coefficient （particle dispersion index, PDI） of 0.623. Chitosan and polyurethane double-shell fragrant microcapsule coated with lavender essential oil has a good release effect compared with pure essential oil and polyurethane single-shell microcapsules.
