| 英文摘要 | In this research, benzotriazole (BTA) is encapsulated as a corrosion inhibitor within bowl-shaped mesoporous polydopamine nanocontainers (MPDA), followed by decorating on the surface of the Ti3C2Tx MXene nanosheets and modifying with 3-aminopropyltriethoxysilane, and the synthesized Silane-MXene@MPDA-BTA is loaded in the weight percentages of 0.1 within solvent-based epoxy coating to apply on the carbon steel. The structure and morphology of the Silane-MXene@MPDA-BTA is considered using transmission electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis. Besides, the corrosion resistance and self-healing performance of the nanofiller loaded epoxy coating are investigated by electrochemical impedance spectroscopy and salt spray tests. The results proved the barrier effect of the prepared MXene-based nanosheets through increasing the low-frequency impedance modulus to 9.76 x 109 ohm.cm2, compared to 9.35 x 105 ohm.cm2 for the blank sample after 60 days of immersion in the 3.5 wt% NaCl solution. Also, the self-healing efficiency of the scratched nanofiller system is about 94.5% (based on changes on charge transfer resistance) after 14 days of immersion. |
