摘要	Polyaniline (PANT) nanofibers were prepared by direct mixed oxidation in four kinds of inorganic acids. The characterization of scanning electron microscopy (SEM) showed that high quality PANI fibers with uniform diameter and several microns length can be obtained by direct mixed oxidation, especially in a sulfuric acid system. Structural characteristics of PANI products through IR and UV spectra indicated the consistent peak distribution with the classic spectrum of the doped PANT. In addition, composite coatings of PANI-epoxy resin were prepared by mechanical grinding. The effect of PANI's content on anticorrosion property of the composite coatings for 0235 steel was studied by the electrochemical impedance spectroscopy (EIS). Results showed that the best shielding protective effect was obtained when the amount of PANT was around 0.5% (wt%). More importantly, the effects of four different inorganic acids on anticorrosion property of the composite coatings were studied by the EIS and Tafel polarization curve. Experiments showed that the different composite coatings of PAN1 doped by different inorganic acids provided different protective abilities for the 0235 steel. It can be concluded that both the morphology and counteranion would impact the anticorrosion effect of the doped PANT.
