摘　　要：介孔氧化硅是最为典型的介孔材料,其具有比表面积高、孔径均一、易于表面修饰等优异特性,广泛应用于吸附分离、催化、传感以及物质负载与缓释等领域。关于粉体和薄膜形态的介孔氧化硅已有大量报道,但纤维形态,特别是连续纤维形态的介孔氧化硅材料的制备仍然是一项挑战。近年来随着静电纺技术的发展,连续纤维形貌的介孔氧化硅材料的制备取得了重要进展。根据纤维介孔结构的有序度和介孔结构引入方式的不同,对静电纺介孔氧化硅基纳米纤维进行详细的介绍。Mesoporous silica is the typical mesoporous material which possesses the excellent advantages of high surface area, uniform pore diameter and ease of surface-functionalization, and has gain much attention on the ap- plications of filtration, catalysis, sensor as well as delivery and releasing. Mesoporous silicas with the morphologies of powder and film have been reported widely. Notably, the preparation of continuous mesoporous silica nanofiber still faces challenges. Benefiting from the development of electrospinning technique, the preparation of mesoporous silica nanofiber achieves great improvement in recent years. The progresses of silica-based electrospun mesoporous nanofiber are generally introduced according to the degree of order of pore structure and routes of introducing mesopores.
