- •
This report identifies an approach of fabricating PEM based on SPES and NPHCs.
- •
The proton conductivity of composite blend membranes, improved with increasing NPHCs content in SPES matrix due to the hydrophilic nature of NPHCs.
- •
The methanol permeability of the fabricated membranes was very low compared to Nafion-117.
- •
The fabricated composite membranes exhibited better electrochemical selectivity than Nafion membranes.
