中文摘要：
聚合物碱性甲醇燃料电池是一种正在兴起的移动电源，氢氧根离子交换膜是碱性甲醇燃料电池的关键材料题之一。从聚二氮杂萘酮醚酮（PPEK）出发，依次采用氯甲基化、溶液法流延成型、三甲胺季铵化和KOH溶液处理等方法，制备了季铵碱型的聚二氮杂萘酮醚酮（QPPEK-OH）电解质膜，测定了膜的电导率和甲醇渗透性。研究发现，每个重复链节中平均含有1.3个季铵碱离子的聚二氮杂萘酮醚酮膜，导电率和甲醇的渗透系数分别为1.14×10^-2S/cm和6.57×10^-7cm^2/s。
英文摘要：
Starting from a high performance polymer of poly（phthalazinone ether ketone）（PPEK）, the quaternized PPEK（QPPEK-OH） membranes for alkaline fuel cells were prepared via chloromethylation,membrane formation,quaternization and alkalization successively. The structure and stability of PPEK derivatives were characterized using 1^H-NMR spectrum and thermogravimetry analysis. For the obtained QPPEK-OH membrane with 1.3 quaternary amine groups in the repeat units of PPEK main chain, the ionic conductivity and methanol permeation coefficient was 1.14 × 10^-2S/cm and 6.57 × 10^-7 cm^2/s respectively.
