Elastic properties of Nafion, polybenzimidazole and poly [2,5-benzimidazole] membranes determined by AFM tip nano-indentation

The mechanical properties of polybenzimidazole (PBI) and poly [2,5-benzimidazole] (ABPBI) membranes, possible candidates to replace Nafion as proton exchange membranes in direct methanol fuel cells (DMFC), were studied. It was observed by AFM imaging that the morphology of the ABPBI membranes strong...
