An aromatic copolymer comprises a hydrophilic segment (A) and a hydrophobic segment (B), wherein the hydrophilic segment (A) comprises a structural unit (1) having a proton conductive group, and the hydrophobic segment (B) comprises at least one structural unit selected from the group consisting of a structural unit (2) and a structural unit (3), wherein the structural unit (2) is a divalent structural unit having an aromatic ring and no proton conductive groups and having two bonding sites at the para-position of one ring included in the aromatic ring, and the structural unit (3) is a divalent structural unit having a benzene ring and is a structural unit different from the structural unit (2), the hydrophobic segment (B) in its entirety contained in the aromatic copolymer including both the structural unit (2) and the structural unit (3).
一种芳香族共聚物包括亲水性片段(A)和疏水性片段(B),其中亲水性片段(A)包括具有质子导电基团的结构单元(1),而疏水性片段(B)包括至少一种从结构单元(2)和结构单元(3)组成的结构单元中选出的结构单元,其中结构单元(2)是具有芳香环但没有质子导电基团的二价结构单元,在芳香环中的一个环的对位上具有两个键合位点,而结构单元(3)是具有苯环的二价结构单元,是不同于结构单元(2)的结构单元,疏水性片段(B)完全包含在包括结构单元(2)和结构单元(3)的芳香族共聚物中。
