In this study, anticorrosion/antibacterial composite coatings were producing by incorporating zinc nanoparticles in epoxy and hybrid resin. Corrosion performance of the nanocomposites coating was evaluated by applying these coatings on carbon steel substrate during sodium chloride salt-spray methods. Adhesion test, scanning electron microscopy (SEM), X-ray fluorescence (XRF), and energy-dispersive spectrometer (EDS) were employed to character these coated with nano-composite substrates. The results of salt spray test showed that nano-zinc in epoxy and hybrid resin could react with permeated oxygen, leading to the improvement of anticorrosion properties of the zinc nanocomposites with addition of desirable of zinc nanoparticles. The corroded area of Zn/epoxy samples more than 80% (without Zn nanoparticle) to less than 5%(3,000 ppm Zn nanoparticle) after 500 hours salt spray test. The bactericidal properties evaluation showed that the bactericidal ability of the Zn/Epoxy, Zn/Hybrid resin nanocomposites with at least 360 ppm of nano-zinc and increased with nano-Zn content remarkably. The corrosion resistant and antibacterial properties are improved with addition of zinc nanocomposites coatings.
