摘要

In this work, epoxy coatings containing phytic acid-doped tetraaniline (PATA) nanoparticles for Q235 steel were prepared and their anticorrosive properties were investigated. Synthesized PATA nanoparticles were characterized by scanning electron microscope (SEM), scanning probe microscope (SPM), photoelectronic spectroscopy (XPS), and Raman test. The anti-corrosion properties of coating were studied by the open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), and scanning vibrating electrode technique (SVET). The experimental results showed that the content of the PATA nanoparticle has a positive effect on the barrier ability of the epoxy matrix. The epoxy coating containing 0.25 wt% of PATA nanoparticles has superior corrosion protection property and a satisfactory self-healing effect. The self-healing effect of PATA/EP coating ascribes to the synergistic effect of the passivation of phytic acid ions and tetraaniline. As an effective anticorrosion filler, the PATA nanoparticle has the potential to apply to the field of corrosion protective coating.
