采用原位合成的方法制备了聚2,5-苯并咪唑(ABPBI)/八氨基笼状倍半硅氧烷(AM-POSS)复合膜材料,并对其化学结构、表面形貌、热稳定性、力学性能、磷酸吸收性能及质子传导性能进行了表征和测试.结果分析认为,与纯ABPBI膜比较,ABPBI/AM-POSS复合膜基体因独特的“八爪鱼”结构而提高了复合膜的热稳定性能和力学强度;AM-POSS粒子的添加还显著提高复合膜的磷酸吸收能力,进而提高了复合膜的质子传导率;ABPBI/3％ AM-POSS复合膜在磷酸掺杂水平达到252％时在80～140℃较宽温度范围内质子传导率超过0.1S/cm;表明AM-POSS改性的ABPBI复合膜具备应用于宽温域质子交换膜燃料电池前景.
