Fig. 5: Counteractive capillary effects for rebound suppression.
From: Suppression of hollow droplet rebound on super-repellent surfaces
a Schematic (left) and pictures displaying the asynchronized deformation of the inner and outer surfaces, which induces capillary flows opposing each other. The dashed yellow boxes highlight the dynamic changes of the dimple shape on the inner surface. b Schematic of the double-spring system that depicts the counteractive capillary effects in HDs. c, d Temporal evolution of the inner (Si) and outer (So) surface areas for HDs at the impact velocity of 0.135 m s−1 (c) and 0.270 m s−1 (d) by numerical simulation. Scale bar, 1 mm.
