双重乳液在许多领域有着巨大的应用潜力。尽管许多公司和研究机构已经开发了用于形成双重乳液的各种策略，但生产和稳定性并不简单。同时，没有一个组织良好的简单设备和可扩展的技术可用于形成高度单分散的双重乳液。在此，我们提出了一种通过组装微交叉装置一步制备高度单分散双重乳液的策略。该装置具有拆装方便、重复性好等优点。由于其高压能力，高通量也很容易实现。此外，我们还系统地研究了三种流速对复乳液尺寸和结构的影响。建立了一个数学模型来预测双乳液的内外液滴尺寸。制备了以甲基膦酸二甲酯（DMMP）为内核，以紫外光固化聚硅氧烷为壳层的阻燃微胶囊。我们希望这种组装的微交叉装置可以在微流体领域得到广泛的应用。
Double emulsions have great potential application in many fields. Although many companies and research institutions have developed various strategies for forming double emulsions, production and stability are not straightforward. Meanwhile, none of the well-organized simple device and scalable technique was available to form highly monodispersed double emulsions. Herein, we present a one-step strategy to produce highly monodisperse double emulsion via assembled micro-cross device. This device has a lot of advantages, such as easy assembly/disassembly and high repeatability. High-throughput is also easily achievable for its high-pressure capacity. Moreover, we systematically studied the effects of the three flow rates on the size and structure of the double emulsions. A mathematical model has been developed to predict the inner and outer droplets size of the double emulsion. We prepared the flame-retardant microcapsules with a dimethyl methylphosphonate (DMMP) inner core and an ultraviolet-curable polysiloxane shell. We hope that this assembled micro-cross device can be employed extensively in the area of microfluidics.
