【摘要】 对蒙脱土进行了有机磺酸化改性和结构表征, 并用于对磺化聚联苯醚砜膜的杂化改性,同时制备了改性蒙脱土(SMMT)/磺化聚联苯醚砜(SPSU)复合质子交换膜,对它们进行的物化和燃料电池性能研究结果表明：有机磺酸化改性使蒙脱土层间距有所增大,有利于改善蒙脱土片层间的有机亲和性和质子传导能力；在 SMMT/SPSU 复合膜中含有较 SPSU 膜更多的键合水, 使膜在升高温度下的含水率提高,改善了膜在高温、低湿度下的质子传导性能,有希望由此开发新的高温质子交换膜。更多还原

【Abstract】 Montmorillonite was organic sulfonated in order to modify the sulfonated polyphenylether sulfone(SPSU) membrane.The sulfonated montmorillonite was characterized by IR and XRD analysis.The SMMT/SPSU composite membrane and SPSU membrane were comparing characterized and investigated.The results show that the interlayer spacing of SMMT was expanded,which is desired beneficial to improve the composite membrane.The SMMT/SPSU composite membrane had more bind water than the SPSU membrane and improved the fuel cell performance under elevated temperature and low humidity condition.更多还原
