Synthesis and Characterization of Sulfonated Polyimides as Proton Exchange Membranes for Fuel Cells
Series of homo- and copolyimides containing controlled degrees of sulfonic acid ion conducting pendant groups have been synthesized from both phthalic (five-) and naphthalic (six-membered) dianhydrides and appropriate wholly aromatic diamines and heterocyclic analogues. The goal is to identify therm...
