A tunable, meta‐linked aryl ether polymer scaffold enables the introduction of various acid groups for a fundamental comparison of their contributions to proton conduction. Sulfonic acid‐functionalized polymers offer the best proton conduction at low temperature and high relative humidity, while phosphonic acid‐functionalized polymers outperform sulfonic and carboxylic acid‐derived polymers at high temperature or low humidity.

在可调聚(亚甲基苯醚)离聚物支架上评估羧酸,膦酸和磺酸的质子部分

可调的,间位连接的芳基醚聚合物支架能够引入各种酸基,从而从根本上比较它们对质子传导的贡献。磺酸官能化的聚合物在低温和高相对湿度下可提供最佳的质子传导性,而膦酸官能化的聚合物在高温或低湿度下的性能优于磺酸和羧酸衍生的聚合物。
