Abstract
Self-assembly in the solution-cast films of binary mixtures of poly(styrene-block-isoprene) (SI) and homopolystyrene (HS) in the dry brush regime was studied by means of transmission electron microscopy (TEM) and light scattering (LS). This self-assembly involves the interplay of the macrophase and microphase transitions. In the case of a low volume fraction of SI, the macrophase separation between SI and HS first takes place via spinodal decomposition (SD) during the solvent evaporation process. This process is subsequently followed by the microphase transition, forming microdomains inside the macrodomains rich in SI. The process is eventually frozen by vitrification
