  Water condensation was studied on silanized (superhydrophobic) and
fluorinated (superoleophobic) micro-rough aluminum surfaces of the same
topography. Condensation on superhydrophobic surfaces occurred via film-wise
mechanism, whereas on superoleophobic surfaces it was drop-wise. The difference
in the pathways of condensation was attributed to the various energy barriers
separating the Cassie and Wenzel wetting states on the investigated surfaces.
The higher barriers inherent for superoleophobic surfaces promoted the
drop-wise condensation. Triple-stage kinetics of growth of droplets condensed
on superoleophobic surfaces is reported and discussed.
