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
