Résumé : A droplet may levitate on its own vapor when dropped on a hot surface. This non-wetting situation is a great opportunity to study the evaporation of complex fluids. In this chapter, we present two case studies in order to evidence general statements about the behavior of complex fluids in Leidenfrost droplets. The first case concerns water and a surfactant mixture. While the droplet is evaporating, it is covered by a thin shell of sodium dodecyl sulfate. Eventually, the droplet explodes. The second case concerns microparticles (glass or basalt). During evaporation, the droplet is encapsulated in a monolayer of grains.
