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 present invention addresses the problem of providing a transparent product which has an anti-glare surface having a surface shape which makes it possible to lower the haze value thereof and to obtain an excellent glare-suppressing effect. The transparent product has a transparent substrate 11 equipped with an anti-glare surface. The surface shape of the anti-glare surface is shaped in a manner such that the ratio (r.sub.0/r.sub.0.2) of the autocorrelation length (r.sub.0), which is the minimum value of the distance r at which the autocorrelation function g(r) represented by formula (1) is 0, to the autocorrelation length (r.sub.0.2), which is the minimum value of the distance r at which the autocorrelation function g(r) is 0.2, is 2 or higher. The autocorrelation function g(r) is obtained by converting the autocorrelation function g(t.sub.x, t.sub.y) obtained by normalizing the surface shape z(x, y) of the antiglare surface to polar coordinates (t.sub.x=r cos Φ, t.sub.y=r sin Φ), and averaging the angle direction. $\begin{array}{c}g\left(r\right)=\frac{1}{2\pi }{\int }_0^{2\pi }d\varnothing .Math.g(r\end{array}$
