摘要：

We examine weakly segregated blends of AB diblock copolymer and A 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 (QPn3m and QIa3d) phases. We find highly swollen phases that we associate with spherical, cylindrical, and lamellar micellar regions, and with disordered struts. © 1995 The American Physical Society.
