Influence of Graphene Oxide on Mechanical and Morphological Properties of Nafion<sup>®</sup> Membranes
Published 2025-01-01“…In exchange, the presence of GO altered the smoothness of the membrane surface going from an average 1.4 nm before the printing to values ranging from 8.4 to 10.2 nm depending on the annealing conditions which could affect the quality of the subsequent catalyst layer printing. Overall, the polymer’s electrical insulation was unaffected, making the Nafion<sup>®</sup>-GO blend a more robust material than those traditionally used.…”
