Drag reduction with different liquids on slippery liquid-infused porous surface

Solid/liquid interface drag reduction is a hot topic and it is of great significance to reduce energy consumption in industrial field. Herein, we prepare a slippery liquid-infused porous surface (SLIPS) with excellent self-healing and super-slippery properties. Through adjusting the density of Zn-Al LDH films on aluminium foil, the ability of rough surface to capture lubricant oil is studied. The SLIPS can repel various liquids such as water,...
