  含氧化膦单元的可溶性磺化聚苯并咪唑作为质子交换膜

  摘要：

  磺化双（4-甲基苯甲酸酯）苯基氧化膦（sBMPO）是通过双（4-甲基苯甲酸酯）苯基氧化膦（BMPO）的磺化和酯化合成的。还制备了一系列高分子量磺化聚苯并咪唑（sPBI-PO）sBMPO、BMPO 和 3,3'-二氨基联苯胺的无规共缩聚。由于聚合物主链不规则排列的重塑，通过在聚合物中加入高浓度的带有苯侧基的苯基氧化膦单元提高了溶解度。sPBI-PO 聚合物显示出优异的机械性能和热稳定性。由于苯基氧化膦单元具有良好的保水能力，制备的 sPBI-PO 膜在 7.4-9.5% 的非常窄的范围内表现出合适的吸水性和出色的尺寸稳定性。随着磺化度的增加，sPBI-PO 的亲水/疏水纳米相分离形貌变得更加明显，如 AFM 相图所示。由于磺化基团和苯并咪唑环之间的强酸碱相互作用，sPBI-PO 膜表现出相对较低的质子电导率。然而，掺杂磷酸后，sPBI-PO90-PA膜的质子电导率为27.62 mS cm-1

  摘要：

  为提高芳香族聚恶二唑(p-POD)纤维的阻燃性能，采用肼法在p -POD主链中引入三芳基氧化膦(TPO)单元，合成了一系列含磷PODs(pho-POD)。以硫酸盐、对苯二甲酸和双（对羧基）苯基氧化膦（BCPPO）为单体，湿法纺丝制得无卤阻燃型pho-POD纤维。采用广角 X 射线衍射 (WAXD)、扫描电子显微镜 (SEM)、热重分析 (TGA)、极限氧指数 (LOI) 等方法对 pho-POD 纤维的结构和性能进行了详细表征和测量。 )、氧弹热量计、热解-气相色谱/质谱 (Py-GC/MS)结果表明， TPO单元的引入导致POD纤维结晶能力减弱，内部结构疏松疏松，热稳定性和力学性能略有下降。然而，LOI 值明显从 28% 增加到 35%，总燃烧热 (GHC) 从 19.72 MJ kg -1下降到 17.84 MJ kg -1随着 BCPPO 内容的增加。此外，pho-POD纤维的燃烧残
