Ks. Alva et al., BIOCHEMICAL SYNTHESIS OF WATER-SOLUBLE POLYANILINES - POLY(P-AMINOBENZOIC ACID), Macromolecular rapid communications, 17(12), 1996, pp. 859-863
This report describes the synthesis of a water soluble polyaniline thr
ough a biochemical synthetic route. The oxidative free radical couplin
g mechanism for the synthesis of poly(p-aminobenzoic acid) is catalyze
d by horseradish peroxidase in the presence of hydrogen peroxide. The
resulting polymer is electrochemically active and undergoes reversible
redox reactions. The polymer as synthesized is self doped and undergo
es undoping in alkaline or ammonia solutions.
