Fabrication of novel self-healable ultraslippery surface for preventing marine microbiologically influenced corrosion

Slippery liquid-infused porous surfaces (SLIPS) have attracted wide attention in the field of marine anticorrosion. However, the stability problem severely restricts the broad applications of SLIPS. Herein, we fabricated a polyurethane-based ultraslippery surface with lubricant self-replenishing and matrix selfhealing properties owing to the huge amount of dynamic hydrogen-bond. Besides, the bacteria culture test and electrochemical analysis results indicate the prepared surface possesses superior properties in the protection of microbiologically influenced corrosion (MIC). This paper offers an efficient strategy to solve stability problem of SLIPS, and the as-obtained self-healable ultraslippery surface can be used as a promising material in mitigating MIC.
