Micellar laccase-catalyzed synthesis of electroconductive polyaniline

Micellar laccase-catalyzed synthesis of electroconductive polyaniline A method of enzymatic synthesis of electroconductive polyaniline on the micelles of dodecylbenzenesulfonic acid sodium salt (DBSNa) is proposed. The high potential laccase from the basidiomycete Trametes hirsuta was used as a biocatalyst. The conditions for polyaniline synthesis were optimized (pH 4.0; reagent concentrations, 10–20 mM; and aniline/DBSNa ratio, 2 : 1). The resulting product was electrochemically active in the range of potentials from −200 to 600 mV, electroconductive, and capable of reversible dedoping with a change in pH of solution. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

A method of enzymatic synthesis of electroconductive polyaniline on the micelles of dodecylbenzenesulfonic acid sodium salt (DBSNa) is proposed. The high potential laccase from the basidiomycete Trametes hirsuta was used as a biocatalyst. The conditions for polyaniline synthesis were optimized (pH 4.0; reagent concentrations, 10–20 mM; and aniline/DBSNa ratio, 2 : 1). The resulting product was electrochemically active in the range of potentials from −200 to 600 mV, electroconductive, and capable of reversible dedoping with a change in pH of solution.
