Enzymatic polymerization of aniline was performed in micellar solutions of the anionic surfactant sodium dodecylbenzenesulfonate (SDBS). High‐redox–potential oxidase–laccase isolated from the fungi, Trametes hirsuta, was used as a catalyst in oxidative polymerization of aniline, the atmospheric oxygen serving as an oxidizing agent. It is shown that the laccase‐catalyzed reaction of monomer polymerization is kinetically controllable and its mechanism is very distinctly different from that of chemical polymerization. The synthesized PANI/SDBS complexes were characterized using Fourier transform infrared and UV–vis spectroscopy, cyclic voltammetry, termogravimetry, transmission electron microscopy, and electron diffraction. The antistatic properties of the prepared PANI/SDBS composite were also studied. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
