Aromatic polyamides have thermal stability and high strength, make themselves attractive in many applications. However, their processability is quite limited due to hydrogen bonding, poor solubility in common organic solvents, and the high melting points. In order to improve the processability, other co-segments can be incorporated into the polymer chain. In this study, crosslinkable random copolymers containing sulfonated poly(phenylene ether sulfone) and m-phenylene isophthalamide were prepared to check the possibility as membrane materials for fuel cell application. Synthesized polymers were transformed into proton exchange membranes. Prepared membranes were characterized in terms of the proton conductivity, ion exchange capacity (IEC), water uptake, methanol permeability, and thermal stability. Detailed results will be presented. |
