Protective Performance

Herein, an intercalation modification technique is proposed to improve the anticorrosion performance of polymeric coatings. Molybdate, an inhibitor, was intercalated to bestow inhibitive attributes, while functionalization of the layered double hydroxide (LDH) reservoir was performed to augment the interfacial adhesion of LDH with the polymer matrix and steel surfaces. The intercalation and functionalization of Mg–Al–LDH was characterized by Fourier-transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis. The corrosion inhibition effectiveness of the prepared composite coating was analyzed using potentiodynamic polarization and electrochemical impedance spectroscopy. The electrochemical results revealed that the protective performance of epoxy coating was significantly enhanced by the addition of functionalized double hydroxide. The corrosion protection efficiency of the composite coating was improved by more than 98%, while the corrosion rate was lowered by ~98%, respectively, with the addition of 1 wt.% of functionalized LDH.
