Abstract
In order to improve the encapsulation efficiency and shell properties of PMMA capsules, poly(MMA-co-TMPTA)/fragrance microcapsules were fabricated by in-situ polymerization with Trimethylolpropane Triacrylate (TMPTA) as the co-monomer. The poly (MMA-co-TMPTA)/fragrance microcapsules were characterized by scanning electron microscopy (SEM), thermogravimetric analyzer (TGA), pyrolysis gas chromatography-mass spectrometer (PGC-MS) and electronic nose (PEN-3). The results indicate that the poly(MMA-co-TMPTA)/fragrance microcapsules present pomegranate shape with rough and sunk surface and have the particle size in the range of 10−20 μm. poly(MMA-co-TMPTA)/fragrance microcapsules has good thermal stability, high encapsulation efficiency of 91.6 % and good slow-release property, and the fragrance on the fabric can be retained for more than 3 months.
