Abstract: | An enzymatic method of producing a conducting polyelectrolyte complex of polyaniline (PANI) and poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) was developed. Acidic stable peroxidase isolated from royal palm tree (Roystonea regia L.) leaves was used as a catalyst in the oxidative polymerization of aniline at pH 2.8. The synthesis procedure was optimized. Spectroscopic and electrochemical characteristics of nanoparticles of obtained PANI/PAMPS complexes at different pH were studied. It was shown that the acidity of the medium affects their properties.__________Translated from Prikladnaya Biokhimiya i Mikrobiologiya, Vol. 41, No. 3, 2005, pp. 283–287.Original Russian Text Copyright © 2005 by Mazhugo, Caramyshev, Shleev, Sakharov, Yaropolov. |
