摘要： 本文通过对聚合物的结构设计, 采用均聚的途径将柔顺的大侧基(甲氧基苯基)引入聚芳醚酮侧链, 然后通过室温后磺化的方法成功制备出侧链型磺化聚芳醚酮材料. 此类材料表现出较好的热稳定性; 力学性能优异; 聚合物的质子传导率比报道过的类似材料有较大程度的提高; 于80 ℃时的质子传导率在0.190 S/cm以上, 超过了Nafion 117 薄膜的传导率(0.175 S/cm). 因此这类材料有望在质子交换膜领域得到应用.

Abstract: A series of poly(arylene ether ketone)s carrying 3-methoxyphenyl side group from 3-methoxy-phenylhydroquinone and difluoro monomers via copolymerization reaction were prepared. Then those polymers were sulfonated by stirring in concentrated sulfuric acid at room temperature. The structure and property of the polymers were characterized and studied. All of the polymers were easity cast into tough membrance. The obtained sulfonated polymers exhibited a good thermal stability, a high proton conductivity(>0.90 S/cm at 80 ℃) and excellent mechanical properties.
