Nanocomposites of polyaniline (PAn) containing nanometer‐size Fe 2 O 3 and CoO were synthesized by a chemical method using sodium dodecylbenzenesulfonate (DBSNa) as a surfactant. Characteristics of the products such as morphology, particle size, and conductivity were studied. The results indicated that these properties were dependent on the surfactant and the type and content of metallic oxide used. When the concentration of Fe 2 O 3 and CoO increased from 1 to 5 g/L in the PAn‐DBSNa/Fe 2 O 3 and PAn‐DBSNa/CoO composites, the conductivity decreased from 1.3 × 10 −4 to 5.1 × 10 −5 and from 1.4 × 10 −4 to 5.1 × 10 −5 S/cm, respectively, while the particle size increased from 92 to 103 and from 104 to 117 nm, respectively.
