Simple Considerations on the Morphology of Ionomers,f the vesicles is examined in detail showing the importance of pores or channels connecting them. The formulas are used to analyze several sets of measurements and allow to extract invariant quantities, namely the number of charges N in a dry ionic domain, or the specific area ∆ covered by an acidic

Statistical Mechanics of Ion-Pair Association in Ionomers, of course, lead to a minimum in the free energy at the equilibrium state. One can think of the free energy change with cluster formation as consisting of three additive components: an energy of cluster formation, an entropy loss due to localization of the ion-pairs within the clusters, and an entro

Chemistry in Ionomers, or PSSA) materials is explored. Their formation, dehydration and reactions with gaseous molecules are illustrated by spectroscopic studies of metal-gas product moieties and reactive intermediates, such as metal carbonyls and hydrides, and by the formation of dispersed metal particles in the ionomer

Chromium (III) and Cobalt (II) Aquo Complexes in PFSA (Nafion) Ionomer Films,on. Electronic derivative spectroscopy was used to probe the changes in the coordination sphere of the cations. Mild dehydration of the hexaaquo Cr(III) complex results in both irreversible hydrolysis giving a hydroxo complex and reversible ligand substitution forming a chromium(III) aquo complex co

Electronic Spectra and Photophysical Properties of Ions as Probes for the Properties and Structure d transient species can each be used to probe the microstructure and physical properties of ionomer membranes. How these measurements have been used to report on changes in the polarity and other properties of the medium in the membranes during such processes as hydration and ion- exchange is descri

Structural Studies of Ionomers by Infrared Spectroscopy, on perfluorinated sulfonate ionomers are reviewed. Infrared spectra, recorded for specimens with different counterions at different water contents and different degrees of deuteration, yield information on the local environment of water molecules and on the structure of the hydrated ion clusters.
