Superhydrophobic Nanoparticles

Researchers have developed synthetic `Slippery Liquid-Infused Porous Surfaces’, known as SLIPS. These are a type of liquid-infused or lubricant-impregnated surface (LIS) that build upon the concept of hemi-wicking. One example is a hydrophobic nanoparticle (superhydrophobic) surface which then locks in place a lubricating fluid which spreads across the substrate. The surface is very slippery because liquid-solid contact is entirely replaced by liquid-lubricant contact.
