Nafion is an important compound that finds application in protein exchange membrane (PEM), serving as a cation conductor. Nafion is an excellent candidate vis-Ã -vis other alternative components for this application since it exhibits exceptional mechanical and thermal stability. Another area that Nafion (resin) has excelled is in the esterification process where it acts as a catalyst. Its choice over other candidates like sulphuric acid is that it does not contaminate the final product, and doesnâ€™t generate wastes by avoiding an ensuing neutralization process synonymous with conventional catalysts.II
In this article we focus our discussions on the synthesis, characterization and the structure-property-performance correlation of a porous Nafion resin nanocomposite. Finally, we will look at one commercial application of this compound as an ionomer.
