Abstract

The richness of spatial structures of the diblock copolymer melts is demonstrated by the minimization of a free-energy functional of nonlocal type. The total chain length and the interface thickness ate key factors in determining the morphology of the system, in addition to the constant mean curvature surface ansatz. We examine the transition between lamellar and double gyroid phases, in which the rhombohedral phase is also obtained in the weak segregation regime.
