Abstract

Abstract Reasonable design of inorganic nano-base materials to promote the anticorrosion performance of waterborne epoxy resin (EP) coating remains a great challenge. Herein, we describe the preparation method and anticorrosion properties of zeolitic imidazolate framework (ZIF-67) composite coatings. ZIF-67 could be used as both anticorrosion filler and pigment for the coatings. The addition of ZIF-67 improved the impermeability of the coating, thus slowing down the chemical reaction on the surface of the substrate. The long-term corrosion-resistant performance of composite coatings (ZIF-67@EP) in 3.5% NaCl solution was evaluated comparatively. Before immersion, the low-frequency impedance of 1% ZIF-67@EP coating was 2.5 times of 0% ZIF-67@EP coating, and after 14 days of immersion, the low-frequency impedance of 1% ZIF-67@EP coating was still 1.8 times of 0% ZIF-67@EP coating. The corrosion rate of 1% ZIF-67@EP coating was decreased by 177 times.
