AbstractLots of two-dimensional (2D) layered materials have become important additives for improving the anticorrosion performance of epoxy coatings for steel structures. In this paper, a 2D MoS2 nanosheet was prepared and treated by sodium dodecyl benzene sulfonate (SDBS) to fabricate 2D MoS2/SDBS composite (2D-MSC) coating on carbon steel. The anticorrosion performance of the coating was comprehensively investigated by contact angle, electrochemical impedance spectroscopy (EIS), X-CT scanning technology and long-term salt spray test. The results showed that 2D-MSC could fill in the natural pores of the epoxy coating, decrease the penetration rate of the corrosive medium into the coating and effectively inhibit the local corrosion rate. Furthermore, the deep working mechanism of 2D-MSC on the epoxy coating was explored by XPS technology. Correspondingly, physical and chemical models were established to illustrate the role that 2D-MSC plays on the coating according to the characterization results.
