Abstract: A separation membrane for selectively separating (e.g., pervaporating) a first fluid (e.g., a first liquid) from a mixture comprising the first fluid (e.g., first liquid) and a second fluid (e.g., second liquid), wherein the separation membrane includes a polymeric ionomer that has a highly fluorinated backbone and recurring pendant groups according to the following formula (Formula I): —O—Rf—[—SO2—N−(Z+)—SO2—R—]m—[SO2]n-Q wherein: Rf is a perfluorinated organic linking group; R is an organic linking group; Z+ is H+, a monovalent cation, or a multivalent cation; Q is H, F, —NH, —O-2 Y+, or —CxF2x+1; Y+ is H+, a monovalent cation, or a multivalent cation; x=1 to 4; m=0 to 6; and n=0 or 1; with the proviso that at least one of m or n must be non-zero.
