交联质子交换膜研究进展

Progress of cross-linking proton exchange membranes

交联是近年来在质子交换膜改性中广泛使用的方法之一,交联可有效控制质子交换膜的水溶胀性,降低膜的甲醇渗透率,增加膜的耐久性,提高膜的力学性能等。作者对质子交换膜的交联方法进行了概述,重点分类讨论了共价交联,离子交联,离子-共价交联和互穿结构交联,并对其研究进展进行了综述。

Cross-linking is one of the widely used methods in proton exchange membranes （PEMs） modification,which is an efficient way to control the water swelling,decrease the methanol permeability,improve the membrane＇s durability and enhance the mechanical properties. In this paper, we have reviewed the progress of cross-linking principles for the proton exchange membrane. These principles above include covalent cross-linking,ionical cross-linking, covalent-ionical cross-linking and interpene-trating structure cross linking.
