摘要
In this paper, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers by in situ intercalation technique and its corrosion inhibition effect was evaluated. The results indicated that the pore structure of GO facilitated the dispersion of LA molecules and improved the volatility. LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization, mainly due to its significant inhibition of the electrochemical anodic process on the surface of mild steel. Moreover, the properties of the surface film on the corroded steel were also characterized in detail to reveal the corrosion inhibition mechanism of LA-GO2.
