Fig. 2. SEM images of different coatings. (a) SEM image of the Nano. (b) and (c) are the exist states of SiC particles in the beetle-like superamphiphobic coating. (b) Reveals that some SiC particles are exposed outside the nano-SiO2 superamphiphobic coating, and (c) shows that although some SiC particle are embedded into the nano-SiO2 particles, and partial regions are exposed, which act as the nucleation sites during the condensation process. (d) Side view of the beetle-like superamphiphobic coating, and the thickness of the coating is ∼21.7 μm to ∼31.2 μm.
