A solid-state NMR study has been used to rationalize the way humidity affects the barrier properties of a polyvinyl alcohol-based membrane. Polymer blends composed of polyvinyl alcohol-polyethyleneimine (PVOH-PEI) and polyvinyl alcohol-polydiallyldimethyl ammonium chloride (PVOH-PDADMAC) were invest...
