Polyaniline/Maleic Acid Copolymers Composites: Synthesis and Characterization

Abstract

Abstract Summary: Polyaniline/maleic acid copolymers composites were synthesized by chemical in situ polymerization of aniline using ammonium peroxidisulfate as oxidant, in the presence of water soluble copolymers containing carboxylic groups. Fine dispersions of composite materials, soluble in N,N‐dimethylformamide or dimethyl sulfoxide were obtained which can be processed as thin films and membranes for application as proton‐conductive materials for electrolyte membranes of fuel cells. The composites were characterized by FTIR spectroscopy and thermal methods.
