Polyaniline (PAN) was doped with sulfosalicylic acid (SSA) and cationic surfactant hexadecyl trimethyl ammonium bromide (CTAB) respectively in this paper. X-ray diffraction (XRD), Fourier transform infrared spectra (FTIR) were used to investigate crystal structure, characteristic groups Measurement of membrane potential showed that SSA and CTAB doped PAN had characteristics of anionic and cationic selectivity respectively. Protective property of the coatings painted on the Q345 steel was investigated by immersing the coatings in 5 wt.% NaCl solution (at 60 °C). Results of electrochemical test and salt spray test indicated that protection of the CTAB doped PAN coating is better than that of SSA doped PAN coating. Its impedance modulus kept constant during all the immersion time. Energy-dispersive X-ray analysis (EDXA) indicated that there was only Na element and few ferrous oxides on the surface of the substrate for the CTAB doped PAN coating. But Cl element and a few oxides appeared on the surface of the substrate for the SSA doped PAN coating.
