Studies on transport properties of polyaniline transition metal salt composites T.D. Kose Polyaniline-containing transition metal salts were synthesized by oxidizing the complex of aniline with corresponding metal salts in solution. The effect of transition metal salts on the electrical conductivity of polyaniline (Pani) was discussed in details. The as-prepared products were characterized by FT-IR spectroscopy. The transition metal has been success-fully incorporated into the polymer, which affects transport properties of the composites; the fact is supported by the ample of experimental results and characterization evidences
