Herein, we report a polymerized ionic liquid diblock copolymer with high hydroxide conductivity and nanoscale morphology. Surprisingly, the conductivity is not only higher (over an order of magnitude) than its random copolymer analog at the same ion and water content, but also higher than its homopolymer analog, which has a higher ion and water content than the block copolymer. These results should have a significant impact on low-cost (platinum-free), long-lasting, solid-state alkaline fuel cells.
在此，我们报道了一种具有高氢氧化物传导率和纳米级形态的聚合离子液体二嵌段共聚物。令人惊讶的是，在相同的离子和水含量下，其传导率不仅高于其无规共聚物类似物（高出一个数量级以上），而且高于其均聚物类似物，后者的离子和水含量高于该嵌段共聚物。这些结果应该会对低成本（无铂）、长效的固态碱性燃料电池产生重大影响。
