| The wetting behavior of a polymer liquid on a coated substrate is investigated via numerical self--consistent field calculations and experiments. The polymer does not wet the coated substrate, but the substrate might stabilized a mesoscopic film. Experiments observe a stable mesoscopic film of nanometer thickness in coexistence with macroscopic drops at high temperatures. Upon cooling, this mesoscopic polymer film breaks up into droplets (nano--dewetting). Our self--consistent field calculations suggest that the stability of the mesoscopic film is determined by a subtle interplay between van--der--Waals forces and short ranged forces due to the distortion of the profile in the vicinity of the substrate. 1 | |||||||||||||
