摘要/Abstract

摘要： 以大孔和超大孔为主的多孔材料因其独特的结构特性在催化、分离、能源、生物医学等领域具有重要的应用价值，但是其在孔结构的控制上仍然存在较大挑战，冰凝诱导法由于操作简单、孔结构容易调控而成为制备多孔材料的重要方法之一。本文从冰凝诱导法制备多孔材料的原理出发，对冰凝诱导制备多孔材料及结构调控、潜在应用、存在问题和展望几个方面进行评述，重点介绍了通过原料组成及浓度、颗粒尺寸、冷冻温度、冷冻速率、溶液环境等手段对孔尺寸及壁厚、孔方向、孔形态的调控，并指出冰凝诱导与其他方法相结合以及进一步功能化是其未来发展的主要方向。

Abstract: Macroporous and megaporous materials exhibit potential application in areas of catalysis,separation,energy,biomedicine and so on,because of their unique structures and properties. Up to now,many methods have been used to prepare such materials. Among them,ice segregation induced self-assembly (ISISA) has attracted great attention because of its unambiguous advantages in pore structure control and operation. In this review,we introduced the preparation mechanism,structure control,potential application,problems and outlook of porous materials by ISISA method. We focused on the regulation of the pore size,direction,morphology and wall thickness of the porous materials by changing the composition of the mixture or freezing conditions. Furthermore,we outlined that combination with other preparation methods and further functionalization of ISISA are two main development directions. This paper will be helpful for readers to understand the research status of ISISA and promote the application and development of porous materials.
