本文通过酸催化缩聚反应，设计并成功制备了一种新型的无碱性C-O键的季铵盐化聚芴哌啶（PBBP）。分别制备了DBMHDA(（AEM-X,X = 1,2,3）、BAPTES（AEM-X, X = 4,5,6）、BPPO （AEM-7）交联的pbbp基阴离子交换膜，并对其性能进行了分析和比较。通过交联，AEM-3和AEM-6表现出明显的微相分离，使得IEC和离子电导率较未改性的AEM-0有所提高。AEM-3在80℃时的电导率为74.7 mS cm（-1）。BAPTES提供的Si-O-Si网络结构可以有效地促进微相分离。AEM-5的IEC仅为1.45 mmol g(-1)，但离子电导率可达60.3 mS cm(-1)，证明膜内存在高效离子通道。然而，实验表明，过度的交联可能会阻碍oh和水分子的运输。BPPO交联的AEM-7具有良好的力学性能和耐碱性，其他方面一般
In this work, a novel quaternized poly(fluorene piperidine)(PBBP) without alkaline labile C-O bonds is designed and prepared successfully via acid-catalyzed polycondensation reactions. The PBBP-based anion-exchange membranes crosslinked by DBMHDA((AEM-X,X = 1,2,3), BAPTES(AEM-X, X = 4,5,6), BPPO (AEM-7) respec-tively are prepared and characterized, and the properties of them are analyzed and compared. By crosslinking, AEM-3 and AEM-6 showed obvious microphase separation, resulting in improvement in IEC and ionic conduc-tivity compared to unmodified AEM-0. AEM-3 shows conductivity of 74.7 mS cm(-1) at 80 ?. the Si-O-Si network structure provided by BAPTES can effectively promote microphase separation. The IEC of AEM-5 is only 1.45 mmol g(-1), but the ionic conductivity of AEM-5 can reach 60.3 mS cm(-1), which proves the existence of efficient ion channels in the membrane. However, experiments have shown that excessive crosslinking may hinder the transport of OH-and water molecules. BPPO crosslinked AEM-7 showed good mechanical properties and alkaline resistance, while mediocre in other aspects
