Evaporation of Water Microdroplets on Self‐Assembled Monolayers: From Pinning to Shrinking

The great escape: Mixed ω-terminated self-assembled monolayers (SAMs) were explored as model surfaces to understand fundamental aspects of liquid evaporation phenomena on solids. The authors demonstrate that on these SAMs the evaporation of water microdroplets follows an exclusive trend. Despite the different wettabilities of the surfaces, the evaporation of water microdroplets switches from a constant contact area (“pinning”) to a constant contact angle mode (“shrinking”).
