Abstract

To address the dual challenges of corrosion and microbial fouling faced by equipment during long-term service in the marine environment, a functionalized MoS₂ synergistic epoxy-based composite protective coating was designed and prepared in this study. MoS₂ was surface-functionalized with KH550 to achieve uniform dispersion within the mixed system of epoxy-modified silicone emulsion and acrylic resin. The effect of MoS₂ loading on the coating's morphology, electrochemical performance, and antibacterial activity against sulfate-reducing bacteria (SRB) were systematically investigated. The results demonstrated that an optimal addition of 5‰ functionalized MoS₂ significantly improved the coating's compactness and uniformity, reducing the corrosion current density to 1.74 × 10^-10 A/cm² and the corrosion rate to 2.0167 × 10^-6 mm/a, thereby exhibiting the best corrosion resistance. Meanwhile, the coating achieved an SRB inhibition efficiency of 96.2% through biofilm disruption, which enable the coating sustainable antibacterial performance. These findings indicate that the functionalized MoS₂ can synergistically exert barrier effect and antibacterial activity in composite coatings, providing both theoretical insights and practical guidance for the development of high-performance marine protective materials.
