Abstract: This work provided a facile strategy to enhance the corrosion resistance of hydrotalcite coating by the chemical modification of the coating with 8-hydroxyquinolate anions. It shows that the chemical modification treatment induces the phase conversion of hydrotalcite coating by the intercalation of corrosion inhibitor into the coating. The hydrotalcite coating with unique layer micro/nanostructure not only serves as an effective template for the chemical modification of the coating, but also acts as a reservoir for the enhanced corrosion protection performance by releasing the accommodated corrosion inhibitor, when it suffers from local corrosion attack in aggressive environments.
