SULFONATED POLYNAPHTHYLIMIDES AS PROTON-CONDUCTING MEMBRANES FOR FUEL CELLS
Main achievements in the field of synthesis of sulfonated polynaphthylimides and their precursors, <i>i.e., </i>sulfonated aromatic diamines, are surveyed. Correlation of the structure of sulfonated polynaphthylimides with their physicochemical parameters, namely, chemical and thermal stability, moisture absorption, ion exchange capacity and proton conductivity, is demonstrated. Polynaphthylimides containing sulfonate groups in the polymer side chains are shown to be promising in producing polymeric proton-conducting electrolyte membranes for fuel cells.
