ABSTRACT

Polymer nanocomposite membranes based on sulfonated poly (ether ether ketone) (SPEEK) and barium strontium titanium oxide (BSTO) have been prepared by solution casting technique. The SPEEK was obtained by direct sulfonation of poly (ether ether ketone) using concentrated sulfuric acid. The degree of sulfonation of SPEEK was determined by ¹H NMR spectroscopy. The composite membranes showed higher water uptake capacity when compared to SPEEK. The ion-exchange capacity of the composite membranes was found in the range between 1.48 and 1.62 meq. g⁻¹. The thermal stability of composite membrane was found to be good enough to use in fuel cell.

用于燃料电池的磺化聚醚醚酮/钡锶钛氧化物聚合物纳米复合膜

摘要

通过溶液流延技术制备了基于磺化聚醚醚酮（SPEEK）和钡锶钛氧化物（BSTO）的聚合物纳米复合膜。SPEEK是通过使用浓硫酸直接磺化聚（醚醚酮）而获得的。SPEEK的磺化度通过¹ H NMR光谱测定。与SPEEK相比，复合膜的吸水能力更高。发现复合膜的离子交换容量在1.48和1.62meq之间。g ^-1。发现复合膜的热稳定性足以用于燃料电池。
