Abstract
It is shown that a certain class of self-affine profiles of surface roughne ss may ren der any substrate with a non-zero microscopic contact angle non- wet, i.e., give it a macroscopic contact angle close to 180 degrees. This i s 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.
