| 中文摘要 | a series of cardo poly(aryl ether sulfone) copolymers bearing pendant hydroxyl ethyl groups (-ch(2)ch(2)oh) were synthesized from a new biphenol monomer 2-(2-hydroxyethyl)-3,3-bis(4-hydroxyphenyl)isoindolin-1-one (pph-oh), 4,4'-biphenol(bp), and 4,4'-difluorodiphenylsulfone (dfdps). sulfonic acid groups were readily grafted to the copolymers by reaction of the hydroxyl group with 1,3-propanesultone. the resulting sulfonated copolymers spes-c-x (where x refer to the content of pph-oh in the bisphenol monomers) contain side chain sulfoalkyl groups (-ch(2)ch(2)-o-ch(2)ch(2)ch(2)so(3)h). tem photographs revealed that spes-c-100 membrane exhibited characteristic hydrophilic/hydrophobic microphase separated morphology with small interconnected and hydrophilic clusters (1.5-2 nm). such microphase separated morphology renders the membrane high proton conductivity of 0.056 s/cm (iec = 1.41 mequiv./g), and low dimensional changes of spes-c-100 at room temperature. spes-c-x membranes exhibited the methanol permeability in the range of 13.8-5.3 x 10(-8) cm(2)/s, which were much lower than those of sbpes (8.7 x 10(-7) cm(2)/s) and nafion 117 (2.4 x 10(-7) cm(2)/s).
