摘要：

Chemical oxidative polymerization of aniline (ANT) by MnO2, PbO2 and NNH4VO3 in aqueous acidic medium led to the formation of polyaniline (PANT). Various acids were used with different strength during the course of polymerization of ANT. FTIR spectral studies confirmed the formation of PANT in each of the polymerization system. Thermogravimetric analyses (TG/DTA) matched with the reported data for PANT obtained from other oxidant systems like (NH4)(2)S2O8 or FeCl3. The do conductivity values were mainly dependent on the nature of acid used in the initial feed of polymerization reaction and it was found that in the case of H3PO4 a conductivity value of 8.0 S/cm could be realized in the present system.
