Fig. 2: States, contact diameters, and contact angles (CA) of droplets on the four hydrophobic surfaces during icing and melting processes.
From: Spontaneous dewetting transitions of droplets during icing & melting cycle
a–c On the SMC surface. d–f On the IMN surface. g–i On the MBNP surface. j–l On the MCNP surface. Orange dashed box marks the recovered air pockets in j. Blue represents the icing processes while orange denotes the melting processes. Black dashed lines mark icing zones and melting zones. Circulation directions are presented by blue arrows (icing direction) and orange arrows (melting direction). The CA 150° boundaries of superhydrophobicity are indicated with black dashed lines. Scale bars and temperatures corresponding to different states are marked. The scale bars of a, d, g and j are 500 μm, 500 μm, 500 μm, and 300 μm, respectively. The fluctuations of the correlation evaluations can be found in the Methods section.
