Résumé : As microscopic grooves or posts on a substrate act as energy barriers during the spreading of a perfectly wetting liquid droplet or film, we are trying to determine whether a groove can actually prevent the liquid spreading out of a certain region on the substrate. It is shown that the confinement of a perfectly wetting volatile liquid within a specific area is indeed possible, and a comparison of the experimentally measured liquid shapes with a static theoretical model is attempted. The role of evaporation, likely to generate finite apparent contact angles, is also discussed.
