• measured underwater OCAs for the nanostructured Ni-CAT-1 and Co-CAT-1 films. The employed liquids are dichloromethane (DCM), dichloroethane (DCE), chloroform (CHCl3) and chlorobenzene (PhCl). For all the tested liquids,a superoleophobicity is observed with underwater OCAs > 150°. A) A 30° tilted SEM top

• , hydrophobic, oleophilic and oleophobic surfaces, and there is no data for superoleophilic and superoleophobic surfaces. In superoleophobicity, the values of the roughness parameters are mostly larger than those of surfaces with hydrophobicity/oleophobicity. As oils are widely used as lubricants and antifreeze

• commercially available superhydrophobic coating system, which was also used to prepare a rough superhydrophilic surface, by subjecting it to vacuum UV (VUV) light treatment. A superomniphobic surface (defined here as a surface exhibiting both superhydrophobicity and superoleophobicity) was created using candle
