It is shown that a certain class of selfaffine profiles of surface roughness may render any substrate with a nonzero microscopic contact angle nonwet ie give it a macroscopic contact angle close to 180 degreesThis is in some contrast to previous work and not only of potential applicational interest but may also contribute to the amazing water repellency of some plant leaves.
