摘　　要：复合介孔二氧化硅膜是近十年来发展起来的一种具有独特孔中孔结构的新型膜材料。该材料以多孔膜(无机多孔膜或者有机多孔膜)为硬模板,以表面活性剂为结构导向剂,通过溶胶-凝胶等方法将介孔二氧化硅材料组装在多孔膜的孔道中制备而成。由于其具有不同于传统介孔二氧化硅膜材料的一些独特结构和性能,并在分离、吸附和催化等领域具有广泛的应用前景,引起了人们广泛的关注。本文主要就复合介孔二氧化硅膜的制备方法,特别是近几年内其在纳滤、纳米材料的模板合成、酶的固定、传感器、反应器以及药物释放等方面最新的应用研究进展进行论述,同时对这类新型的复合介孔二氧化硅膜材料在合成和应用方面存在的问题进行了分析和总结,并对其发展前景作了展望。Hybrid mesoporous silica membranes, in short HMSMs, are a kind of novel membrane materials with unique structure of pores-in-pores synthesized by sol-gel, evaporation-induced self-assembly, aspiration-induced infiltration, counter diffusion self-assembly, vapor-phase synthesis and microwave-assisted synthesis methods. Such hybrid mesoporous silica membranes are composed of mesoporous silica materials inside the confined channels of porous membranes including organic porous membranes and inorganic porous membranes employed as the hard templates. In addition, various surfactants are used as the structure directing agents （SDA）. Due to the different structure of HMSMs with pores-in-pores from those conventional mesoporous silica membranes and their attractively potential applications in the membrane-based adsorption, filtration and catalysis etc. , those hybrid mesoporous silica membranes have attracted great attention during the past decade. This review focuses on the recent developments of this kind of novel hybrid membranes including the synthesis methods and the applications in the membrane-based nanofiltration, templated-syntheses of nanomaterials, enzyme immobilization, artificial biomembrane, sensor, reactor and drug delivery etc. Additionally, some problems found in the syntheses and the applications of such hybrid mesoporous silica membranes are analyzed and concluded in this review. Moreover, the development prospect of this kind of hybrid mesoporous silica membranes is discussed.
