Interfacial tension plays an important role in microfluidic emulsification, which is the process of preparing emulsions. A promising method which controls droplet behavior according to the function of the interfacial tension in the process of microfluidic emulsification is reported. The droplet size and generation frequency changed regularly to obtain appropriate concentrations of surfactant. This method could be of great help for setting up the size-controllable droplet generation systems, and ameliorating the emulsification technology. The interfacial tension effect was first analyzed by computational simulation before the real experiment, which significantly improved the efficiency of the whole research process.
界面张力在微流控乳化中起着重要作用，微流控乳化是制备乳液的过程。本文报道了一种有前景的方法，该方法根据微流控乳化过程中界面张力的功能来控制液滴行为。通过改变界面张力，可以规律地改变液滴的大小和生成频率，从而获得合适浓度的表面活性剂。该方法对于建立可控尺寸的液滴生成系统和改进乳化技术有很大的帮助。在进行实际实验之前，首先通过计算模拟分析了界面张力的影响，这显著提高了整个研究过程的效率。
