- W2091973075 abstract "Abstract In this paper the properties of water and of large organic ions or neutral molecules confined within the perfluorinated membrane Nafion are studied by electron spin resonance of nitroxide probes. The membrane was used in conditions of full hydration and after exchange with mono- and di-positive ions. The analysis was mainly based on the ESR lineshapes and the correlation times for the motion of positive, neutral, and negative radicals. The dependence of the lineshape on the charge of the probe and on the charge of metal ions was analyzed as a function of temperature. The behavior of adsorbed water was similar to that observed in other systems in which the liquid was finely dispersed. The decreased polarity of sorbed water as a consequence of the lower strength of the hydrogen bond, suggested by A. Falk (Canad. J. Chem. 58, 1495 (1980)) was confirmed from the AN values of nitroxides. These were located in ionic clusters and were exposed to the interactions with pendant fluorocarbon chains. The extent of these interactions depended on the charge of either the nitroxides or the exchanged metal ion. The ESR patterns invariantly arose from the superposition of many absorptions due to radicals showing different motional rates and in slow exchange among different sites. This indicated the presence of ionic clusters of variable sizes in which water moved with different diffusion coefficients. The comparison between the ESR results and the previously reported NMR results confirmed the nonuniformities in the membrane structure." @default.
