三嵌段共聚物和由其制备的电解质膜
摘要：
本发明提供三嵌段共聚物和由其制备的电解质膜。该三嵌段共聚物具有含有极性部分的共聚物嵌段/含有非极性部分的共聚物嵌段/含有极性部分的共聚物嵌段或者含有非极性部分的共聚物嵌段/含有极性部分的共聚物嵌段/含有非极性部分的共聚物嵌段的结构，并且可用于燃料电池用的电解质膜。由所述三嵌段共聚物制备的燃料电池用的电解质膜表现出优异的尺寸稳定性和优异的燃料电池性能。
摘要（英）：

Provided are a tri-block copolymer and an electrolyte membrane prepared therefrom. The tri-block copolymer has a structure of polar moiety-containing copolymer block / non-polar moiety-containing copolymer block / polar moiety-containing copolymer block, or non-polar moiety-containing copolymer block / polar moiety-containing copolymer block / non-polar moiety-containing copolymer block, and is useful for an electrolyte membrane for fuel cells. The electrolyte membrane for fuel cells prepared from the tri-block copolymer exhibits superior dimensional stability and excellent fuel cell performance.
