Figure 16

Realization of superamphiphobicity by the combination of femtosecond laser ablation and chemical etching method. (a) Schematic diagram of preparation process of superamphiphobic microstructure. (b–d) Morphology of the 3D reentrant nanograss on laser-structured microcones. (e) Photo of a water droplet and a dodecane droplet on the resultant surface. (f, g) Variation of the wettability of the as-prepared superamphiphobic surface on the surface tensions of different liquids. Reproduced from [113] with the permission.
