| 英文摘要 | Steel corrosion is a main factor that significantly affects the durability of reinforced concrete. To overcome this limitation, an eco-friendly corrosion inhibitor, ferulic acid and methionine modified chitosan (CTS-FA-Met) with a dual-function protection mechanism of anodic complexation regulation and interfacial film formation was elaborately designed and synthesized. The corrosion inhibition effect and mechanism of CTS-FA-Met were systematically analyzed by weight loss, electrochemical performance, surface morphology and complexation tests, as well as theoretical calculations. Experimental results showed that CTS-FA-Met effectively reduced the corrosion rate of steel, with a maximum inhibition efficiency of 96.89 %. The -NH2 and -OH groups in CTS-FA-Met effectively complexed with Fe2+, achieving a maximum adsorption capacity of 68.68 mg/g, and the complexation process could be well described by the pseudo-secondary-order (PSO) kinetic model and the Langmuir isothermal model. Theoretical analyses revealed that the heteroatoms (O and S) in CTS-FA-Met donated electrons to the vacant d-orbitals of Fe, forming covalent bonds that promoted stable adsorption on the Fe surface to isolate corrosive substances. The purpose of this study is to provide new strategies for inhibiting steel corrosion and to offer eco-friendly and sustainable insights for improving the durability of reinforced concrete. |
