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, wefabricated a polyurethane-based ultraslippery surface with lubricant self-replenishing and matrix selfhealingproperties owing to the huge amount of dynamic hydrogen-bond. Besides, the bacteria culturetest and electrochemical analysis results indicate the prepared surface possesses superior properties inthe protection of microbiologically influenced corrosion (MIC). This paper offers an efficient strategy tosolve stability problem of SLIPS, and the as-obtained self-healable ultraslippery surface can be used asa promising material in mitigating MIC.
