Underwater superaerophobicity of fish scale and underwater superaerophilicity of lotus leaf. (a) Small bubble on the fish scale in water. (b) Process of an underwater bubble rolling off a fish scale. (c–f) Formation mechanism of the underwater superaerophobicity: (c) water wetting the hierarchical microstructure of fish scale, (d) fish scale in water, (e) releasing a bubble onto the surface of the fish scale in water, and (f) after a period of time. (g) Process of a bubble spreading out on a lotus leaf in water. (h–k) Formation mechanism of the underwater superaerophilicity of lotus leaf: (h) water siting on the hierarchical microstructure of lotus leaf, (i) lotus leaf in water, (j) releasing a bubble onto the surface of the lotus leaf in water, and (k) after a period of time.
