In this work, Poly o-anisidine nanoparticles was prepared by using cationic surfactant. Poly o-anisidine nanoparticles/ nanocomposites filled with constant content 1.0 wt% of Ag₂O, ZnO, CuO and TiO₂ powder have been prepared. The sample microstructure was established by FTIR spectroscopy and transmission electron microscopy. The thermal properties, sulfate reducing bacteria and electrical conductivity were investigated. The influence of the inorganic nanoparticles on the thermo stability of poly o-anisidine nanoparticles is very complicated. It was found that POA/Ag₂O nanocomposite microspheres have good effects to sulfate reducing bacteria than POA nanoparticle. The value of the electrical conductivity, σ, of the nanocomposites was investigated. It was found that the poly o-anisidine nanoparticles was improved by adding metal oxides which converted the polymer nanoparticles from insulator behaviour 10^-16(S/cm) to semiconductor behaviour 10^-11(S/cm) in case of POA/Ag2O and 10^-12 (S/cm) in case of POA/ZnO. The conductivity was increased by increasing the temperature.
