摘要
共价有机框架(COFs)作为一种新型有机多孔材料,具有高度结晶性、有序的多孔排列、功能可修饰性、结构可调性以及较高稳定性.COFs规整的孔道可以容纳多种质子载流子和质子供体,构建连续稳定的质子传输通道,在含水质子传导与无水质子传导中均发挥巨大的作用,将COFs应用到质子交换膜领域具有重要的研究意义和价值.本文分别从COFs作为低温燃料电池质子交换膜和高温燃料电池质子交换膜两方面,总结了 COFs固态电解质膜、COFs与高分子基质复合膜、COFs自支撑膜等不同种类质子交换膜的特点以及提高COFs质子交换膜性能的改性方法,综述了近年来COFs在燃料电池质子交换膜领域的相关代表性研究.最后,对COFs质子交换膜的应用前景进行了讨论与展望.
Abstract
Covalent organic frameworks(COFs),as a new type of organic porous materials,are highly crystalline and orderly porous,exhibiting functional modifiability,structural tunability and high stability.The regular pore channels of COFs can accommodate a variety of proton carriers and proton donors to build continuous and stable proton transport channels,playing a great role in both aqueous and anhydrous proton conduction.The application of COFs to the field of proton exchange membranes is of great research significance and value.In this paper,the characteristics of different types of proton exchange membranes,such as COFs solid electrolyte membranes,polymer matrix-COFs composite membranes,COFs self-supporting membranes and the modification methods to improve the performance of COFs proton exchange membranes are summarized from the aspects of COFs as proton exchange membranes for low temperature fuel cells and high temperature fuel cells,respectively.The relevant representative research of COFs in the field of fuel cell proton exchange membranes in recent years is reviewed.Finally,the application prospects of COFs proton exchange membranes are discussed and prospected.
