摘要: 本文通过对聚合物的结构设计,采用亲和取代的途径制备了含有甲氧基侧链的聚芳醚聚合物,然后去醚化得到了侧链含有羟基的聚芳醚材料,最后通过接枝的方法将磺酸基团引入聚合物成功的制备出多磺化侧链型聚芳醚质子交换膜材料。此类材料表现出好的热化学稳定性, 80 oC时的质子传导率可达到0.192 S/cm,超过了Nafion 117 薄膜的传导率.同时此类材料表现出低的尺寸稳定性。因此此类材料很有希望在质子交换膜领域得到应用

关键词: 磺化聚芳醚酮, 质子交换膜, 燃料电池

Abstract: poly(arylene ether ketone) carring multi-sulfonated side chain was prepared via graft polymerization reaction. The obtained soluble sulfonated polymer SP-I and SP-II have high viscosity (ηinh >1.72dL/g). The transparence and tough sulfonated polymer film was obtained by solution casting method and exhibited good thermochemical stability, high proton conductivity(>0.90 S/cm)and good dimensional stability.

Key words: sulfonated poly(aryl ether ketone)s, proton exchange membranes, fuel cell
