Abstract
Wetting and dewetting of structured and imprinted surfaces is discussed fro m a theoretical point of view. An appropriate separation of length scales i s used in order to eliminate irrelevant parameters from the theory. This le ads to a general description of the wetting phase which can exhibit various morphologies such as droplets, channels or films. We discuss some general features of heterogeneous surfaces, extended surface domains, and line tens ion effects. We emphasize (i) the new concept of morphological wetting tran sitions, which occur both for small and for large surface domains; and (ii) the importance of studying the scale-dependence of the wetting morphologie s as one zooms down into the nanoregime.
