Aniline was oxidized to polyaniline salt using benzoyl peroxide as an oxidizing agent in the presence of acids such as sulfuric, nitric, or hydrochloric acid by aqueous polymerization pathway. Polyaniline salts, their corresponding bases and redoped polyaniline salts were characterized by infrared, electronic absorption, x‐ray diffraction spectral techniques, elemental analysis and conductivity measurement. The result of this study indicates that both acid and surfactant group are present in the polyaniline salt as dopants. Polyaniline salts with reasonable yield (around 80%) and conductivity (0.04 S/cm) were prepared. Copyright © 2004 John Wiley & Sons, Ltd.
