The slippery liquid infused porous surfaces (SLIPS) with employing pitcher plants as a biomimetic prototype are ultra-smooth surfaces formed by injecting lubricants into rough porous structures with low surface energy. Owing to the excellent barrier effect, the SLIPS lubricating layer has a good application prospect in the field of metal corrosion protection. In this work, the construction mechanism of SLIPS was introduced, and the preparation methods of SLIPS on metal surfaces were summarized from three aspects: direct substrate structuring, in-situ growth and coating treatment. The anti-corrosion applications of SLIPS on four different metal surfaces of aluminum, copper, magnesium and steel were reviewed. Furthermore, the shortcomings of SLIPS materials used in metal anti-corrosion were pointed out, and its development trend was prospected.
