A water‐dispersible conducting polyaniline/ nano‐SiO 2 composite, with a conductivity of 0.071 S cm −1 at 25°C, was prepared by the oxidative polymerization of aniline in the presence of amorphous nano‐SiO 2 particles. And the structure, morphology, thermal stability, conductivity, and electroactivity of this composite were also investigated. This composite has been steadily dispersed in the aqueous solution for about 10–36 h without the need for any stabilizer. It would significantly impulse the commercial applications of conducting polyaniline/nano‐SiO 2 composite as fillers for antistatic and anticorrosion coatings. © 2007 Wiley Periodicals, Inc.
