制备具有受控液滴尺寸和内部结构的多重乳液长期以来一直是一个挑战。然而，近年来，在通过小规模流体加工制备单分散单乳液方面取得了重大突破，这使得能够形成具有所需液滴尺寸、结构和组成的多重乳液。本文综述了在各种微结构装置中制备受控多重乳液的方法。分别讨论了四种制备途径。它们是（a）膜乳化，（B）微通道乳化，（c）使用二维微流体装置，和（d）使用三维同轴微毛细管装置。本文还讨论了所制备的多重乳液在一类新型材料中的应用。
The preparation of multiple emulsions with controlled droplet sizes and internal structures has been a challenge for a long time. However, in recent years, a major breakthrough has been achieved in the preparation of monodisperse single emulsions by small-scale fluid processing, which has enabled the formation of multiple emulsions with the desired droplet sizes, structures, and compositions. This review deals with the preparation of controlled multiple emulsions in various microstructured devices. The four preparation pathways are discussed individually. They are (a) membrane emulsification, (b) microchannel emulsification, (c) the use of a two-dimensional microfluidic device, and (d) the use of a three-dimensional coaxial microcapillary device. The applications of the prepared multiple emulsions to a novel class of materials are also discussed.
