Cation-exchange membranes: comparison of homopolymer, block copolymer, and heterogeneous membranes
Original language description
Three types of sulfonic cation-exchange membranes were compared: (a) homogenous membranes prepared by sulfonation of 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 of the sulfonated products, (b) membranes prepared by sulfonation of poly[styrene-block-(ethene-stat-butene)-block-styrene] film, and (c) heterogeneous membranes prepared by melt-blending linear polyethylene and particles 10-25 ?m particles of sulfonated cation-exchanger followed by compression molding. At the same ion-exchange capacity (IEC), the membranes based on the block copolymer showed considerably higher ionic conductivity than the homogeneous membranes. Though having a higher IEC, the heterogeneous membranes were less conductive than the other investigated membranes. Their advantage consists in the ease of preparation and superior resistance to oxidative environment.
