Carbon NMR investigation of the polybenzimidazole–dimethylacetamide interactions in membranes for fuel cells

Abstract

Polybenzimidazole dissolved in dimethylacetamide has been studied by 1H and 13C one and two dimensional NMR methods to investigate the polymersolvent interactions. The resonance signals have been fully assigned, giving a complete picture of the present species and allowing a study of the involved dynamic processes. The results have been correlated with the formation of H-bonds, and with the presence of tautomeric processes in the polymer.
