Pinned contact line
Webb15 feb. 2024 · The detailed height profiles close to the “coffee stain” area (Fig. 3 c) confirm the thickness depression in the centre and suggest that the contact line is permanently pinned and that the drop dries in accordance with the simulations performed by Park et al. [22] The experiments imply that the formation of the gelled region at the edge does not … WebbA pinned contact line means that the outer edge of the liquid drop, where it intersects the solid substrate, remains stationary as the drop evaporates. Evaporation is caused by heat in the substrate and is greatest at the thin outer edge of the drop.
