【摘要】 通过聚芳醚砜的改性和功能化，制备了一系列不同交联程度的离子簇型阴离子交换膜（cQPSF-bisQAxTAPy），通过¹H NMR和FT-IR确定了聚合物的结构.结果表明：cQPSF-bisQAx-TAPy具有较好的成膜性和明显的微相分离结构，其凝胶分数在50.8%～68.5%范围，离子交换容量（IEC）值可达到2.07～2.35 mmol·g^-1.在80℃下，吸水率（WU）、溶胀率（SR）和离子传导率（σ）分别为83.0%～192.6%、20.3%～58.8%和112.7～173.7 mS·cm^-1.cQPSF-bisQAxTAPy的初始分解温度约为180℃，拉伸强度为9.79～20.11 MPa，断裂伸长率为11.1%～20.3%，在60℃的1 mol·L^-1NaOH溶液中浸泡7 d后，σ可以保持初始的90.3%～93.2%.cQPSF-bisQAx-TAPy具有较高的离子传导率的同时，还表现出良好的尺寸稳定性、碱性稳定性、机械性能和热性能.更多还原

【Abstract】 A series of ionic cluster anion exchange membranes （cQPSF-bisQAx-TAPy） with different degrees of crosslinking were prepared by modification and functionalization of poly（arylene ether sulfone）,and the structures of the copolymers were characterized by¹H NMR and FT-IR.The results indicated that the cQPSF-bisQAx-TAPy had good filmforming properties and well-defined nanophase separation,with gel fractions in the range of 50.8%-68.5%and the ion exchange capacity（IEC）reaching 2.07-2.35 mmol·g^-1.Water uptake（WU）,swelling ratio（SR）and ion conductivity（σ）were in the range of 83.0%-192.6%,20.3%-58.8%and 112.7-173.7 mS·cm^-1at 80℃，respectively.The initial decomposition temperature of cQPSF-bisQAx-TAPy was around 180°C.The tensile strength was 9.79-20.11 MPa,while the elongation at break were 11.1%-20.3%,and theσcould be maintained at 90.3%-93.2%of the initial value after 7days of immersion in 1 mol·L^-1NaOH at 60°C.Besides high ionic conductivity,cQPSF-bisQAx-TAPy also exhibited excellent dimensional stability,alkaline stability,mechanical properties and thermal properties.更多还原
