We described a facile approach to rapidly achieve the reversible oil wettability and adhesion transition on the copper substrate. Plasma treatment and surface fluorination were used to tune the surface composition, and this tunability of the surface composition, along with the stable surface roughness, gave rise to the switchable wettability varying from superoleophobicity to superoleophilicity and reversible oil adhesion between sliding superoleophobicity and sticky superoleophobicity. It took only 1.25 min to realize the whole wettability transition and 5 min for the whole adhesion transition. Additionally, the application of a sticky superoleophobic surface was demonstrated. This study represents an important addition to the field of functional superoleophobic materials.
