The problem addressed by the present invention is to provide an antifogging coating film having excellent antifogging property, antifogging persistence, persistence of appearance, and elution resistance. The coating film according to the present invention contains a metal oxide (A) and a hydrophilic compound (B); the height of the eluate by a coating film surface elution test is 1.0 μm or less; this test is carried out by placing 10 μL of deionized water on the coating film, allowing the film to stand for 24 hours in a 23° C., 50% RH environment, measuring the eluate height of 20 locations selected randomly within a 10 cm.sup.2 range on the coating film surface, and determining the maximum height; and the water contact angle measured after subjecting the coating film to a moisture resistance test by exposure for 24 hours in an 85° C., 85% RH environment followed by standing for one hour in a 23° C., 50% RH environment, is less than 40°. Preferably, the elution level per coating film unit volume by a coating film total elution test is 40 mg/cm.sup.3 or less, and this test is carried out by immersing the coating film in 23° C. deionized water for 24 hours, then measuring the weight of the coating film eluate recovered from the deionized water.

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.
