Abstract:

A kind of multifunctional nanocomposite coating based on setae-spatulae structure of gecko is innovatively proposed, which was prepared by blending method. Potential polarization curve, electrochemical impedance spectroscopy (EIS) and salt spray test were analyzed respectively to analyze the corrosion inhibition effects. Results indicated that the impedance at low frequency region of epoxy resin (EP)/ZnO/Fe2O3 (γ-type) nanocomposite coating was the highest, which is 5.17 times of that of epoxy resin. Nanocomposite coating with multi-scale and multi-component nanoparticles has better pulverization resistance than blank epoxy resin and one-component coatings. The degree of protection of EP/ZnO/Fe2O3(γ-type) was highest.
