Molchanov, V. Roldughin, I. Chernova-Kharaeva] Experiments have been performed on the formation of ring-shaped deposits by evaporating droplets of dispersions using the coffee ring effect. The experiments have been carried out with aqueous dispersions of polystyrene and silica submicron particles, as well as SiO2 particles of the Levasil brand with a size of 50 nm. It has been shown that there are three different scenarios of deposit formation and droplet meniscus displacement. The deposits may be formed as rings and disks. When ring-shaped deposits are formed, the displacement of the meniscus may be essentially different (from the periphery to the center of the droplet and vice versa) depending on the nature of particles. The mechanisms responsible for the realization of different scenarios have been considered at the qualitative level. Pleiades Publishing, Ltd., 2015 Molchanov S.
