Abstract  

Nano-ZnS was prepared by hydrothermal method and polyaniline was prepared by chemical oxidation respectively, which then were blended to prepare a series composite materials of polyaniline modified by nano-ZnS. Finally the relevant composite coatings were applied on Q235 carbon steel. The acquired composite materials and coatings were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The electrochemical corrosion performance of the composite coatings in 3.5% (mass fraction) NaCl solution was investigated by potentiodynamic polarization and electrochemical impedance. The results showed that the nano-ZnS was uniformly dispersed in the polyaniline matrix and therewith the anticorrosive performance of the coatings was improved significantly. Among others the coating with 50% (mass fraction) ZnS exhibited the best anticorrosive performance with a protection efficiency 99.9% after immersion in 3.5%NaCl solution for 7 d. Besides, after immersion for 30 d, the coating surface morphology changed obseriously, but the coating is still dense and could provide good protectiveness for the substrate material even up to 30 d.
Key words:  polyaniline      nano-ZnS      disperse      corrosion protection
