Abstract

The interplay of phase separation, preferential wetting, and capillary instability in thin film polymer blends is investigated using composition-profiling and surface-imaging techniques. The phase-separating films exhibit a unique morphology with two evolving lateral length scales at both the free film surface and the interface between the coexisting phases, with the growth kinetics of the smaller structures appearing slower at the free film surface.
