微流控技术由于具有优异的流体微尺度相界面调控能力，是实现微结构精确可控的新型功能材料的设计制备与性能调控的重要新兴手段。本文介绍了微流控技术可控构建稳定相界面结构的两大体系：一是具有封闭液-液相界面的乳液液滴体系；二是具有非封闭层状和环状液-液相界面的层流体系。回顾了利用微流控技术构建的这两类稳定相界面结构体系制备三大类功能材料的研究进展：一是利用乳液液滴体系制备微球微囊材料；二是利用层状层流体系制备微通道膜材料；三是利用环状层流体系制备超细纤维材料。指出微流控技术为实现功能材料的小尺度化、薄膜化、纤维化、多功能化、材料元件一体化等带来了新的机遇，提出应进一步深入系统地认识液-液相界面设计与调控以及功能材料合成过程的基本规律和机理。

Microfluidic technology is an efficient tool to control micro-scale phase interfaces precisely;therefore it is an important novel approach for design,preparation,and performance regulation and control of new functional materials with controllable micro-structures. In this paper,the controllable construction of two types of stable micro-scale phase interfaces with microfluidics is introduced. One type is the emulsion droplet system with enclosed liquid-liquid phase interface,and the other type is the laminar flow system with non-enclosed layered and annular liquid-liquid phase interface. The progress of preparation of three categories of functional materials with these two types of microfluidics-generated stable phase interface architectures as templates is reviewed , including fabrication of microspheres and microcapsules with emulsion droplets as templates,preparation of membranes in microchannels with layered laminar flow systems as templates,and synthesis of microfiber materials with annular laminar flow systems as templates. Microfluidic technology brings new opportunities for the realization of small-scale features and multi-functions of functional materials,ultra-thin membranes and ultra-fine fibers,and integration of materials and components. In the future,further in-depth and systematic understanding of design and regulation of the liquid-liquid phase interfaces as well as the regularities and mechanisms in the synthesis processes of functional materials should be emphasized.
