A fundamental understanding of polymer microstructure is important in order to design novel polymer electrolyte membranes (PEMs) with excellent electrochemical performance and stabilities. Hydrocarbon-based polymers have distinct microstructure according to their chemical structure. The ionic clusters and/or channels play a critical role in PEMs, affecting ion conductivity and water transport, especially at medium temperature and low relative humidity (RH). In addition, physical properties such as water uptake and dimensional swelling behavior depend strongly on polymer morphology. Over the past few decades, much research has focused on the synthetic development and microstructural characterization of hydrocarbon-based PEM materials. Furthermore, blends, composites, pressing, shear field, electrical field, surface modification, and cross-linking have also been shown to be effective approaches to obtain/maintain well-defined PEM microstructure. This review summarizes recent work on developments in advanced PEMs with various chemical structures and architecture and the resulting polymer microstructures and morphologies that arise for potential application in fuel cell, lithium ion battery, redox flow battery, actuators, and electrodialysis.

烃基聚合物电解质膜：离子输运和膜稳定性的形态学重要性。

为了设计具有优异的电化学性能和稳定性的新型聚合物电解质膜（PEM），对聚合物微观结构的基本了解很重要。烃基聚合物根据其化学结构具有独特的微观结构。离子簇和/或通道在PEM中起关键作用，特别是在中等温度和低相对湿度（RH）的情况下，会影响离子传导性和水的传输。另外，诸如吸水率和尺寸溶胀行为的物理性质在很大程度上取决于聚合物的形态。在过去的几十年中，许多研究集中在基于烃的PEM材料的合成开发和微观结构表征上。此外，共混物，复合材料，压制，剪切场，电场，表面改性，交联和交联也已被证明是获得/维持明确的PEM微观结构的有效方法。这篇综述总结了有关具有各种化学结构和结构的高级PEM的最新进展，以及由此产生的聚合物微结构和形貌，这些潜在的潜在应用是在燃料电池，锂离子电池，氧化还原液流电池，促动器和电渗析中。
