Conducting polyaniline (PANI) doped with H4SiW12O40 was obtained in the polyglycol (PEG) aqueous solution and PEG ethanol solution, respectively. The PANI was characterized by IR, XRD patterns and UV-Vis spectra. The conductivity of the PANI was measured by the four-probe method. The effect of the ratio of heteropoly acid (HPA), oxidant and aniline, and the temperature of the reaction system on the final yield, conductivity, and solubility of the PANI was investigated, respectively. The results showed that the performance of PANI synthesized in ethanol was better than that in water. The highest conductivity of the PANI prepared in ethanol was 1.87 S/cm. The soluble ratio of the PANI was 53%.
