A chemical pattern on a substrate is transposed into thin films of a ternary polymer blend during spin-casting from a common solvent. One of the blend components intercalates at interfaces between the other two phases to reduce their interfacial energy. As a result, an extensive substructure is formed, in addition to domains with pattern periodicity λ. Morphologies with well-ordered lateral domains are created not only when the inherent scale of the phase domains R is comparable to λ (as observed previously) but also for , extending pattern transposition to smaller length scales.
