大直径W1/O/W2乳粒的稳定性
Stability of large diameter W1/O/W2 emulsion particles
摘要
Abstract
W1/O/W2 double emulsion particles of around 2 mm diameter were prepared using emulsion microencapsulation method. The stability of the particles was studied under the quasi-static condition and the rotating flow field, respectively, with the variation of the organic phase concentration and the water-soluble polymer concentration. The enhancement mechanism of the kinetic stability of the particles was explored based on force analysis and deformation analysis. The results show that, both under the quasi-static condition and the rotating flow field, the stability of W1/O/W2 double emulsion particles increases with the in-crease of PS concentration. However, it increases firstly and then decreases when PVA concentration increases. Moreover, in some conditions, the kinetic stability of W1/O/W2 double emulsion particles is greatly enhanced in the rotating flow field com-pared with under the quasi-static condition.关键词
