摘要	The self-healing performance of anticorrosive coatings is critical to restoring their protective function in the event of failure to ensure durability in harsh corrosive conditions. In this work, a novel self-healing an-ticorrosive coating was fabricated by two-dimensional transition metal carbides and carbonitrides (MXenes) and mesoporous silica nanoparticles (MSNs) loading tannic acid (TA) as corrosion inhibitors that can effectively protect low-carbon steel from corrosion damage. The TA as corrosion inhibitors were loaded into the mesoporous silica nanoparticles, and the loading capacity reached about 71.71%. The synthesized epoxy/TA@MXene-SiO2 coating was characterized in detail using different tools. The epoxy/TA@MXene-SiO2 coating had excellent anticorrosive performance and an impedance modulus of 2.826 x 10(6 )omega cm(2) at 0.01 Hz. The impedance modulus reached the maximum peak value of 8.585 x 10(6) omega cm(2) after 132 h of continuous immersion. In addition, the TA made a coating with an electrochemical self-healing efficiency of 114.27 kS2 cm(2) h(-1). This work provides insight into the novel design of anticorrosive coatings with excellent anticorrosive performance and high self-healing efficiency. (C) 2022 Elsevier B.V. All rights reserved.
