Synthesis of H₃PW₁₂O₄₀•xH ₂O-doped polyaniline by chemical oxidative polymerization

With different concentration of H₃PW₁₂O ₄₀• xH₂O, conducting polyaniline (PANI) was synthesized by chemical oxidative polymerization. The samples were characterized by FT-IR, UV-vis spectroscopy and four-point conductivity measurement. The FT-IR and UV-vis spectra showed that all the samples possessed the characteristic of doped PANI. The conductivity of PANI was dependent on the concentration of H₃PW₁₂O₄₀• xH ₂. The maximum value of conductivity was about 1.28×10 ^-2 S/cm when the experimental concentration of H₃PW ₁₂O₄₀• xH₂ was 4 mg/mL. The results show that polyaniline doped with H₃PW₁₂O₄₀• xH₂ was successfully prepared by chemical oxidative polymerization.
