By using chemically heterogeneous prestructured substrates, made by micro-contact printing, any pattern can be used to induce a compositional variation in the polymer film (see Fig. 1). Thus, by controlling the phase morphology, one can create surfaces with new properties so that those systems are applicable for lithography masks, optical components or biological sensors. In addition, a laterally isotropic phase separation can lead to new physical properties. For instance, if we remove one of the two polymers having a morphology with a lateral
