The Schiff base, N-salicilidenoanilina was used as dopant to induce polymerization of aniline and thus preparing polyaniline (PAni). The different conditions of preparation, including Schiff base structure, and the dosage of acidity reaction medium, were investigated to discuss the influence of these conditions relative conductivity of the resulting samples. The products were also characterized by Fourier transform infrared (FTIR), ultraviolet-visible (UV-Vis), electrochemical impedance spectroscopy (EIE). The results showed the synthesis conditions play an important in the formation and the final properties of the polyaniline
