Coating compositions are provided that eject droplets of condensed fluid from a surface. The coatings include a nanostructured coating layer and in some embodiments, also include a hydrophobic layer deposited thereon. The coating materials eject droplets from the surface in the presence of non-condensing gases such as air and may be deployed under conditions of supersaturation of the condensed fluid to be ejected. A heat exchanger design utilizing the coating is described herein.

The invention relates generally to liquid-repellent coatings, and in particular, to porous liquid-repellent coatings, a method of preparing the porous liquid-repellent coatings, and a method of characterizing a porous surface for the liquid-repellent coatings. The invention further relates to a porous liquid-repellent coating comprising a porous layer of a transition metal oxide and/or hydroxide and a layer of a liquid-repellent compound deposited onto the porous layer of the transition metal oxide and/or hydroxide, wherein the porous layer of the transition metal oxide and/or hydroxide is comprised of a plurality of surface pores of varying angles with an average angle that is re-entrant.
