摘要: 在准静态条件和旋转流体场中采用乳液微封装技术制备约2 mm的大直径W1/O/W2乳粒，研究了有机相浓度和水溶性聚合物浓度对W1/O/W2乳粒稳定性的影响。从乳粒受力和变形的角度，探索了旋转流体场对W1/O/W2乳粒动力学稳定性的增强作用机制。研究表明：无论是在准静态条件下还是旋转流场中，乳粒稳定性都随聚苯乙烯浓度单一上升，随聚乙烯醇浓度呈现先上升后下降的趋势；相对于准静态条件，旋转流体场在一定条件下对大直径W1/O/W2乳粒的动力学稳定具有明显增强作用。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 increase 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 compared with under the quasi-static condition.
