1H Solid-State NMR Study of Nanothin Nafion Films
Abstract
The unique behaviors of Nafion nanothin films with thicknesses of 10 nm (ultrathin) and 160 nm (thin) were evaluated using variable-temperature and variable-humidity solid-state 1H NMR spectroscopy. These unprecedented measurements of nanothin films stacked within an NMR rotor represent a remarkable experimental achievement and demonstrate that 1H NMR spectroscopy of such minute amounts of ionomer might be possible within active catalyst layers …
