【摘要】 两性质子交换膜是一种含有酸、碱结构并具有质子传导功能的聚合物薄膜材料。由于其结构可设计性强,分子链特殊的相互作用使之在导电的同时对甲醇或钒离子等具有优异的阻隔性能,近年来引起了广泛的关注。本文对国内外相关的研究结果进行了评述,并对两性质子交换膜进行了定义,根据化学结构和制备方法将其分为三大类:(1)碱性聚合物与高沸点酸掺杂型;(2)酸、碱聚合物共混型;(3)含有酸碱结构的聚合物本征型,对其在质子交换膜燃料电池和全钒液流电池中的应用性能进行了讨论。更多还原

【Abstract】 Amphoteric proton exchange membrane is a kind of polymer membranes with proton-conducting function,which contains both acidic and basic structure.Strong structural design and special interaction of molecular chains make it excellent blocking performance of methanol or vanadium ion while conducting,has caused wide attention in recent years.In this paper,the relevant research results at home and abroad were reviewed,and the amphoteric proton exchange membrane was defined.According to chemical structure and preparation methods,it was divided into three types:(1)alkaline polymer and high boiling acid doping type,(2)acid and alkaline polymer blends,and(3)the intrinsic properties of polymers containing the acid-base structure,and their applications in proton exchange membrane fuel cells and vanadium redox flow batteries were discussed.更多还原
