| Abstract: | Polyaniline/silica composite particles was synthesized by chemical oxidation of aniline using hydrogen peroxide containing tungstic acid peroxide as a homogeneous catalyst in the presence of silica and hydrochloric acid as the doping acid. The dosage of the oxidant, the molar concentration of hydrochloric acid, the weight ratio of aniline to silica and the reaction time on the yield and conductivity of composite particles were studied. The structure of polyaniline/silica composite particles was identified by FF-IR, and its appearance was characterized with the method of SEM. |
