Ion-exchange properties of polypyrrole doped by ω-carboxylated polyethyleneoxide

α-Methoxy ω-Na carboxylate polyethylenoxide (f-PEO) has been synthesized and used as counter-ion for the synthesis of polypyrrole (PPy) films. The effect of f-PEO concentration on the kinetics of pyrrole polymerization has been studied. The ion exchange properties of the formed PPy/f-PEO composite have been analyzed in aqueous solution containing various salts (f-PEONa and LaCl3). The incorporation of indigo carmine in this type of composite has also been investigated.
