Sulfonated aromatic polymers (SAP) have been shown to be promising materials for proton exchange membranes (PEM) due to their high thermal and chemical stability as well as lower-cost production compared to commercial available perfluoro sulfonated polymers. Two key main steps to achieve high-performance PEM of SAP are sulfonation of the aromatic polymer and subsequent membrane crosslinking techniques. In this review, the common post-sulfonation methods for development of SAP and the state of the art crosslinking procedures are mostly covered. This review is targeting to bring the reader up to date of all available techniques. To obtain an overview is especially important, because no single sulfonation and/or crosslinking procedure can be considered ideal in all cases, and for each SAP the best method is dependent on the type of polymer and its applications.

相比于市售的全氟磺化聚合物，磺化芳族聚合物（SAP）具有高的热稳定性和化学稳定性以及较低的生产成本，因此已被证明是用于质子交换膜（PEM）的有前途的材料。实现SAP高性能PEM的两个关键主要步骤是芳族聚合物的磺化和随后的膜交联技术。在这篇综述中，大多数涵盖了开发SAP的常用后磺化方法和最新的交联程序。这篇评论的目的是使读者了解所有可用的技术。获得概述尤为重要，因为在所有情况下都无法将单个磺化和/或交联程序视为理想选择，
