Abstract

The ordering mechanisms for an ABC triblock copolymer system are studied using self-consistent field theory. We find a two-phase mechanism, similar to what has been suggested experimentally 􏰖two-step mecha- nism􏰌. Analysis of free energy components shows that the two-phase process comes about through a compe- tition between stretching energy and interfacial energy. The mechanism is found to be sufficiently robust so as to make it potentially useful for device applications.
