Abstract: Surface and bulk changes in Nafion membranes as a result of IL-cation doping (1-butyl-3-methylimidazolium tetrafluoroborate or BMIM+BF4- and phenyltrimethylammonium chloride or TMPA+Cl−) was studied by X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC) and impedance spectroscopy (IS) measurements performed with dry samples after 24 h in contact with the ILs. BMIM+ and TMPA+ IL-cations were selected due to their similar molecular weight and molar volume but different shape, which could facilitate/impede the cation incorporation in the Nafion membrane structure. The surface coverage of the Nafion membrane by the IL-cations was confirmed by XPS analysis, and the results obtained by the other two techniques seem to indicate differences in thermal and electrical behaviour depending on the doping-cation, being less resistive the Nafion/BMIM+ membrane. For that reason, determination of a characteristic electrochemical parameter as the ion transport number was obtained for this membrane by measuring the membrane or concentration potential with the samples in contact with HCl solutions at different concentrations and the results compared with an untreated Nafion membrane.
