Analysis of the hydration process and rotational dynamics of water in a Nafion membrane studied by 1H NMR spectroscopy.

Abstract

(1)H NMR spectroscopy is employed to reveal the hydration process of a Nafion membrane by measuring both the chemical shift and the spin-lattice relaxation time. In a former study, the hydration process was suggested to comprise two steps: the molecular adsorption of water on the sulfonic acid groups and wetting with liquid water. The present study has… (More)
