✦ Synopsis

have shown how a rough surface can influence the apparent contact angle at the boundary between a liquid and the surface, and many examples have been given of the difficulty of wetting rough surfaces because of their large apparent contact angles. The wettability or water-repellency of porous surfaces has not been similarly investigated although it is of much importance for the rain resistance of all porous clothing, both natural and artificial. The present paper extends Adam and Wenzel's analysis to porous surfaces.
