摘要:

采用界面聚合法,以聚脲为壁材包覆薰衣草香精,制备得到薰衣草纳米胶囊。透射电子显微镜(TEM)分析表明,制备的薰衣草纳米胶囊为规则球形,且具有明显的核壳结构。粒径分布分析可以看出薰衣草纳米胶囊的平均粒径为131.7 nm,粒径分布PDI为0.16。傅里叶变换红外光谱(FT-IR)和紫外-可见光谱也证明了薰衣草能被很好地包埋在纳米胶囊中,且包埋率高达96.5%。热重分析(TGA)和高温缓释曲线表明,包覆在纳米胶囊中的薰衣草在150 ℃开始挥发,具有良好的热稳定性和缓释性能。此外,经薰衣草纳米胶囊整理的棉织物在皂洗150 min后仍具有良好的耐洗性。

Abstract:

The lavender fragrance nanocapsules were successfully prepared via the interfacial polymerization method using polyurea as the wall material to coat the lavender oil. Transmission electron microscope(TEM)images reveal that the nanocapsules possess regular spherical morphology with distinct core-shell structure, indicating that lavender oil is well encapsulated in the nanocapsules. And particle size distribution analysis shows that the average particle size of the lavender nanocapsules is approximately 131.7 nm with particle size distribution PDI of 0.16. Fourier transform infrared spectroscopy(FT-IR)and ultraviolet-visible analysis also show that the lavender oil can be well encapsulated inside the nanocapsules and the encapsulation efficiency of the nanocapules is as high as 96.5%. The thermal gravimetric analysis(TGA)and high temperature sustained-release curves indicate that the lavender oil encapsulated in the nanocapsules began to volatilize at 150 ℃ with good thermostability and sustained-release properties. Additionally, cotton fabrics treated with the fragrance nanocapsules display good washability after 150 min of soaping.

Key words: lavender oil, polyurea, nanocapsule, sustained release, fragrant fabric
