Stability of hierarchical lamellar morphologies formed in ABC star triblock copolymers

Abstract The stability of hierarchical lamellar morphologies formed in ABC star triblock copolymers, is studied using the self‐consistent mean‐field theory. The hierarchical lamellae consist of repeating period of the largest block A‐formed layer and B/C coformed layer where B and C domains are arranged alternatively. An angle, which is used to characterize the shifting magnitude between two neighbor B/C coformed layers, varies from 0 to 180 …
