原始语种摘要: Abstract(#br)This research examined how the physical properties of Nafion ® are affected by mixture casting Nafion ® with quaternary phosphonium salts. Quaternary phosphonium salts can be mixture cast with commercially available Nafion ® suspension to form membranes with decreased proton exchange capacity and altered mass transport of cations, anions and neutral species through the membrane. Since quaternary phosphonium salts are similar in size and hydrophobicity to quaternary ammonium salts, the mass transport of cations, anions and neutral species through tetraethylphosphonium bromide and tetrabutylphosphonium treated Nafion ® is similar to tetraethylammonium bromide and tetrabutylammonium treated Nafion ® , respectively. Although there is no statistically significant difference...
