摘　　要：模板结合自组装方法在获得聚合物表面有序孔结构和实现聚合物表面孔结构的各种应用方面具有简单方便的特点.本文介绍和评述了通过形成乳液的方法,将水分散到聚合物的溶液中,并利用乳液的动态融合和界面能的平衡作用,伴随溶剂的挥发过程,实现水滴的有序阵列作为模板的有序多孔膜的制备.与自上而下的水蒸气模板法不同,乳液模板法的优势是引入的稳定剂同时也是孔内表面的修饰剂,可以实现孔结构的表面同步自组装修饰和新组分引入.本文也介绍了乳液模板法在表面有序孔结构应用方面的新特性.Surface ordered porous polymer films have shown the great application prospect in the fields of optoelectronic devices, separation, bioscience, filtration and medicine. Among the various kinds of self-assembled methods, water droplet template approach has been widely investigated owing to its easy operation, wide application and low cost features. In this paper, we present and review the preparation of ordered porous polymer films via microemulsion method and the functionalization of cavity structures. We firstly introduce the development of microemulsion approach, the detail preparation procedures, morphology and dimension of ordered porous surfaces which usually exhibit hexagonal close packed honeycomb structures at several micrometers. Then we discuss the influence factors of preparation for ordered cavity structures, such as the surfactant, solvent, water content, droplet dimension and so on, and after that we provide the formation mechanism of porous films through microemulsion method utilizing the dynamic integration, thermal capillary force and interface energy balance concepts. Further, we discuss the modification method of cavity inner surface which realizes the local assembly of diverse functional water-soluble components into the cavities by just adding these compounds into water phase of emulsion solution, and several kinds of water soluble components have been adopted, such as polyoxometalates and proteins. We also list some characterization methods for cavity decoration, for example, EDX analysis which can be used to test the location of large mass or high content elements, and CLSM images which can be adopted to detect the positon of fluorescent molecules. Then, we review the current applications of cavity structures, for example, using the components within the cavities to complete specific recognition of proteins and construction of protein microarray, constructing glucose-responsive insulin delivery system by adopting the modified cavities as the drug reservoir, and fabricating cell pattern thro
