This short review summarizes the literature on composite anion exchange membranes (AEM) containing an organo-silica network formed by sol-gel chemistry. The article covers AEM for diffusion dialysis (DD), for electrochemical energy technologies including fuel cells and redox flow batteries, and for electrodialysis. By applying a vast variety of organically modified silica compounds (ORMOSIL), many composite AEM reported in the last 15 years are based on poly (vinylalcohol) (PVA) or poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) used as polymer matrix. The most stringent requirements are high permselectivity and water flux for DD membranes, while high ionic conductivity is essential for electrochemical applications. Furthermore, the alkaline stability of AEM for fuel cell applications remains a challenging problem that is not yet solved. Possible future topics of investigation on composite AEM containing an organo-silica network are also discussed.
这篇简短的综述总结了关于含有通过溶胶-凝胶化学形成的有机硅网络的复合阴离子交换膜（AEM）的文献。文章涵盖了用于扩散渗析（DD）、包括燃料电池和氧化还原液流电池在内的电化学能源技术以及电渗析的AEM。通过应用各种各样的有机改性硅化合物（ORMOSIL），过去15年报道的许多复合AEM都基于用作聚合物基质的聚乙烯醇（PVA）或聚（2,6-二甲基-1,4-苯醚）（PPO）。最严格的要求是DD膜具有高选择透过性和水通量，而高离子电导率对于电化学应用至关重要。此外，用于燃料电池应用的AEM的碱性稳定性仍然是一个尚未解决的具有挑战性的问题。还讨论了含有有机硅网络的复合AEM未来可能的研究主题。
