Study of the conduction mechanisms at the PANI /PAMPS interface. Role of m-cresol

The interface between polyaniline (PANI) and a polymer electrolyte (PAMPS) containing functionalized sulfonate anions (AMPS) presents a particular structure (double-strand polymer) allowing the transfer of carriers, even when PANI is oxidized up to an insulating form. The conduction is detected by the growth of an IR optical absorption. The role of a PANI treatment by m-cresol is investigated.
