2018-7-13 · The physical and gas-transport properties of Fe3+ cross-linked Nafion meranes were examined. Wide-angle X-ray diffraction results revealed a lower crystallinity for Nafion Fe3+ but showed essentially no changes in the average chain spacing upon ion exchange of Nafion H+. Raman and Fourier transform infrared spectroscopy techniques qualitatively measured the strength of the ionic …
