Summary: The use of cerium-zirconium oxide nanoparticles in epoxy coatings shows excellent corrosion resistance, with the addition of zirconium enhancing the corrosion inhibition properties. The corrosion resistance of zirconium-doped ceria-epoxy coatings improves with an increase in the doping concentration of Zr for Ce-rich solid solutions. The improved redox properties of ceria-zirconia solid solutions due to a large number of oxygen vacancies contribute to their corrosion inhibition properties.

Summary: In this study, the effects of doping different acids on the corrosion resistance of polyaniline/epoxy composite coatings were investigated. It was found that the doping acid has a significant influence on the corrosion resistance and passivation performance of the coatings. PANI-SSA/WEP coatings exhibited the highest impedance value and showed significantly enhanced protective performance, which can be attributed to the oxidation-reduction reversibility of PANI-SSA and the inhibition functionality of the released sulfosalicylic acid.

Summary: In this study, polyaniline-cellulose nanofiber (PANI-CNF) nanocomposites were successfully prepared by polymerization of aniline on TEMPO oxidized CNFs. These nanocomposites were added to waterborne epoxy resin to fabricate composite coatings with different contents of PANI-CNFs. The corrosion resistance of the coatings was evaluated and the results showed that the composite coatings containing 0.5% PANI-CNF exhibited the best corrosion resistance even after 40 days of immersion in NaCl solutions.

Summary: A waterborne epoxy coating with self-healing and anti-corrosion properties was developed using nanocomposites of (GO@(PDA + KH-550)-Zn). The coating exhibited high impedance values and a low corrosion rate. The self-healing ability of the coating was verified through electrochemical impedance spectroscopy (EIS) tests, which showed the repair of intermediate scratches. The release of corrosion inhibitors and the unique self-healing mechanism of the composite coating contributed to its excellent performance.

Summary: A simple and effective method for obtaining OH-functionalized mica nanosheets (MNs) was developed, which involved calcination, plasma treatment, and ultrasonic exfoliation, resulting in a yield of 7.535%. The effects of sonication time, solvent type, and particle sizes of mica on the preparation of MNs were investigated. The conditions for the preparation of MNs were determined: mica calcination, plasma treatment, and sonication in ethanol for 5 h. XPS and FT-IR demonstrated that more hydroxyl groups were introduced to mica after the plasma treatment, which facilitated the exfoliation of mica.
