Textured substrates infiltrated with a lubricant form a new class of functional surfaces, known as lubricant-infused slippery surfaces. They are promising candidates for low adhesive, anti-icing and anti-fouling surfaces.

To design durable slippery surfaces, a better understanding of the interplay between the physical and chemical interactions among the surface topography, the lubricating film and the droplet under static and flow conditions is essential. After an introduction on how to chemically modify surfaces, the basic concepts to model wetting of smooth, and rough surfaces will be introduced.

This includes advancing, receding contact angles, tilting angles, and lateral adhesion forces. The consequences of a lubricating film will be discussed, including the Neumann triangle, spreading coefficient, capillary forces and elastic forces. Different mechanisms of adhesion will be introduced. Analytical and numerical methods to describe adhesion are going to be presented, including mesoscopic (Lattice Boltzmann method) and macroscopic (scaling analysis and lubrication theory) approaches.

The Innovative Training Network (ITN) Lubricant-Impregnated Slippery Surfaces (LubISS) has as main objectives the designing, characterization, and modelling of these slippery and low adhesive surfaces.
