摘要: Three types of sulfonic cation-exchange membranes were compared: (a) homogenous prepared by sulfonation poly(2,6-dimethyl-1,4-phenylene oxide) or poly[oxy(1,4-phenylene)oxy(1,4-phenylene)carbonyl(1,4-phenylene)] and solution casting the sulfonated products, (b) poly [styrene-block-(ethene-stat-butene)-block-styrene] film, (c) heterogeneous melt-blending linear polyethylene particles 10–25 μm cation-exchanger followed compression molding. At same ion-exchange capacity (IEC), based on block copolymer showed considerably higher ionic conductivity than homogeneous membranes. Though having a IEC, less conductive other investigated Their advantage consists in ease preparation superior resistance to oxidative environment. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
