Figure 1. Superamphiphobic membranes.

(a) Schematic representation of a superamphiphobic gas membrane. The effective gas/liquid interface is highlighted in red. (b) SEM images of a stainless steel mesh (c–e) and after coating with an approximately 35 μm thick superamphiphobic layer. (f) Cross-section of the mesh showing that the wires are partially embedded in the layer. We did not observe an influence of the thickness of the coating on the gas exchange rate or on the anticlogging behaviour of the layer for thicknesses above 15 μm. Scale bars, 500 μm (c), 40 μm (d), 3 μm (e) and 60 μm (f).
