Superhydrophobic Nanoparticles

Schematic illustration of superhydrophobic nanoparticles

When a layer of hydrophobic nanoparticles is infused with a liquid such as silicone oil, the resultant surface is very slippery because liquid-solid contact is entirely replaced by liquid-lubricant contact. These surfaces are called `Slippery Liquid-Infused Porous Surfaces’, known as SLIPS. They are a type of liquid-infused or lubricant-impregnated surface (LIS) that build upon the concept of hemi-wicking.
