Recent developments in slippery liquid-infused porous surface

Slippery liquid-infused porous surface (SLIPS) has attracted increasing interest in anti-icing, anti-corrosion, anti-fouling, and surface omniphobicity, in view of its superior stability and performances as compared to the conventional superhydrophobic surface. It is thus of paramount importance to analyze and summarize the most recent progress to boost its further development and applications. This review begins with the bio-inspired design of the SLIPS system with reference to the conventional superhydrophobic counterparts, and outlines a number of fabrication strategies by introducing liquid or solid lubricant into surfaces of different wetting features. The typical applications are summarized and compared towards oil/water separation, anti-icing, anti-fouling, anti-corrosion, and other emerging trends. The future perspectives are discussed based on the state-of-the-art studies at the end.
