| 英文摘要 | CO2 and other corrosive media have been confirmed by studies as significant factors that accelerate steel and concrete corrosion. Therefore, anti-corrosion coatings are required not only to resist the penetration of corrosive solutions but also to provide resistance against gas permeation. In this study, a kind of TiO2-GO/PU composite coating was developed via a hydrothermal method, and its chemical bonding and thermal decomposition behavior were characterized. The results indicated that the mass ratio of GO and TiO2 in TiO2-GO was 68.25% and 31.75%, and crosslinking occurred between TiO2-GO. Carbonation tests demonstrated that the addition of TiO2-GO significantly enhanced the CO2 permeation resistance of the PU coating, with the 0.3% content showing the most noticeable improvement. Electrochemical impedance spectroscopy revealed that after immersion in 3.5 wt% NaCl solution, the coating incorporated with TiO2 exhibited highest barrier properties compare with other samples. Meanwhile, the incorporation of TiO2-GO improved the pull-off adhesion and wear resistance of the coating. SEM observations of the exposed coatings showed that the 0.3% TiO2-GO/PU coating had intact surface, confirming its optimal anti-corrosion performance. These improvements were attributed to defect sealing, microcrack suppression, extended diffusion pathways, and the anchoring effect of TiO2 that mitigates GO layer slippage. This study offered a long-term, economical, and efficient anti-corrosion solution in marine environments. |
