Polyaniline in its conductive emeraldine salt form (PANI–ES) has good dispersibility in water phase, thermal and radiation stability. The enzymatic oxidation of aniline or aniline dimer ( p–aminodiphenylamine, PADPA), in the presence of dispersed anionic soft–interfaces– also called “templates”– in slightly acidic aqueous solution is expected as environmentally–friendly process for PANI–ES production. Without templates, these products do not form. Laccase/O2–catalized synthesis of PANI–ES in the presence of sodium bis(2–ethylhexyl)sulfosuccinate (AOT) vesicles as templates is advantageous in its simple procedure, and low concentration of required enzyme. The effect of four different templates under their respective optimal conditions was investigated and compared in a systematic way. The templates used were sulfonated polystyrene (SPS), micelles from sodium dodecylbenzenesulfonate (SDBS), vesicles from SDBS/decanoic acid (DA) and vesicles from AOT. Although all four templates carry a sulfonate group and yield PANI–ES–type products, there are clear differences in the properties of the product mixtures obtained. AOT vesicles performed as the best template in the viewpoint of produced amount and chemical stability of polarons (radical cations) in PANI–ES–like products.
