Enhancement of the anti-corrosion performance based on the zeolitic imidazolate framework

In this work, a zeolite-imidazole framework (ZIF-8) was first synthesized and used as a corrosion inhibitor container to enhance the anti-corrosion property. After encapsulated the benzotriazole (BTA) corrosion inhibitor and coated with epoxy resin (EP) on the surface of Cu plate, the obtained sample B-ZIF-8@EP exhibited enhanced corrosion protection with high impedance and positive self-corrosion potential due to the release of BTA in the corrosion process. It is believed that this work is very helpful for extending the diversity of anti-corrosion coatings.
