在这项工作中，我们用一步微流控装置制备了油包水包气（G/W/O）多核双重乳液，并发现了一种新的稳定的流动模式，其中多核双重乳液很容易制备。对这种特殊流型的形成机理进行了探讨。此外，我们还系统地研究了三种流速对双乳液粒径和结构的影响。然后，我们开发了数学模型来预测双重乳液的尺寸和结构。在此基础上，采用原位紫外光聚合法成功制备了多孔聚丙烯酰胺水凝胶微球.该方法为制备多孔微球提供了一种简单而新颖的方法。
In this work, we generated gas-in-water-in-oil (G/W/O) multi-cores double emulsions with a one-step microfluidic device and found a new stable flow pattern, where multi-cores double emulsions were easily fabricated. The mechanism of the particular flow pattern was discussed. Moreover, we systematically studied the effects of the three flow rates on the size and structure of the double emulsions. We then developed mathematical models to predict the size and structure of the double emulsions. On this basis, porous polyacrylamide hydrogel microspheres were successfully fabricated byin situUV polymerization method. This method provides a simple and novel approach to produce porous microspheres.
