ELECTROCHEMICAL SYNTHESIS OF POLYANILINE POLY(2-ACRYL-AMIDO-2-METHYL-1-PROPANE-SULFONIC ACID) COMPOSITE

Conducting polyaniline/poly(2-acryl-amido-2-methyl-1-propane sulfonic acid) (PANi/PAMPS) composite films were synthesized electrochemically on platinum electrodes using a 10% aqueous PAMPS solution as the electrolyte. The electrochemical properties of the resulting polymer are similar to those observed for polyaniline doped with classical non-polymeric anions. PANi/PAMPS exhibits high cycling stability within the potential range of the first redox couple, but it undergoes degradation when the potential range characteristic of the second redox couple is reached. The degradation occurs independently of the electrolytic medium (HCI or 10% aqueous PAMPS).
