Abstract

A magnetic nanocontainer (Fe_xCo_3-xO₄) loaded with corrosion inhibitor molecules (benzotriazole, BTA) was prepared through a hydrothermal method, and a pH-controlled release system was designed (Fe_xCo_3-xO₄@BTA-Cu). Under the 300 mT magnetic field distribution, the Fe_xCo_3-xO₄@BTA-Cu can be evenly distributed in the epoxy coating. In addition, a hybrid coating with superhydrophobic and bactericidal properties was prepared on the surface of the first coating with evenly distributed magnetic particles. Compared with the pure EP coating, the composite coating exhibits superior corrosion resistance and self-healing performance. Moreover, the underlying anticorrosion, superhydrophobic, anti-icing, and antibacterial mechanisms of the composite coating were analyzed in depth.

期刊介绍： Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
