Stability of Ordered Phases in Weakly Segregated Diblock Copolymer Systems
Abstract
Stability of ordered phases in diblock copolymer melts is studied using a theory of anisotropic fluctuations, which bears a useful similarity with energy band theory in solids. We calculated stability lines of all ordered phases and found the hexagonally perforated lamellar phase to be unstable around the lamellar-cylindrical (LC) phase boundaries. We used fluctuation analysis to obtain dynamical pathways between ordered phases and argue that …
