SiWn Co/Polyaniline （PAn） was synthesized by co-insertion of HCl together with substituted heteropolyanion. Its thermal stability, fluorescence property, conductivity, cyclic voltammetric behavior and magnetism were investigated. The results revealed that SiW11 Co/PAn had better thermal stability. Its decom- position temperature is about 162 ℃ higher than that of PAn base. The conductivity of the material is 0. 54 S/cm. It has reversible electrochemical property. Its saturation magnetization is higher than that of the heteropolyacid, and at the same time, the system shows paramagnetism.
