Abstract
We examine weakly segregated blends of diblock copolymer and homopolymer using self-consistent field theory. The addition of homopolymer to a diblock melt is found to stabilize new ordered morphologies: close-packed spheres, hexagonally perforated lamellae, and bicontinuous cubic ( and ) phases. We find highly swollen phases that we associate with spherical, cylindrical, and lamellar micellar regions, and with disordered struts.
