Block copolymers are theoretically characterized using the self-consistent field theory and a Monte Carlo and dynamic approach inspired by the self-consistent field theory. The self-consistent field theory approach is used to evaluate a ternary system of diblock copolymers with each homopolymer. Swelling effects and phase behavior are studied in both the bulk and thin films.

520 $a Block copolymers are theoretically characterized using the self-consistent field theory and a Monte Carlo and dynamic approach inspired by the self-consistent field theory. The self-consistent field theory approach is used to evaluate a ternary system of diblock copolymers with each homopolymer. Swelling effects and phase behavior are studied in both the bulk and thin films.
520 $a A particle-based Monte Carlo formalism for the study of polymeric melts is derived from the local density functional that appears in the field-based model. The model is particle-based but the interaction is derived from a local density functional that appears in the field-based model. The method enables Monte Carlo simulations in the nVT, nPT, semi-grandcanonical and Gibbs ensembles and direct calculation of free energies. In the first use of this approach, we consider the phase separation of a binary homopolymer blend and present results for the phase diagram and the critical point. Next, we address the microphase separation of a symmetric diblock copolymer, examine the distribution of local stresses in lamellae and determine the order-disorder transition temperature.
520 $a Our third Monte-Carlo study is in the nPT-ensemble and the Gibbs ensemble on symmetric ternary mixtures of AB-diblock copolymers with the corresponding homopolymers. We study the lamellar period by varying the length and amount of homopolymers. The homopolymer distribution within the lamellar morphology is determined as is the maximum amount of homopolymer within the lamellae. Gibbs ensemble simulations are used to locate the three-phase coexistence between two homopolymer-rich phases and a lamellar phase. We discuss the implications of the results with respect to short-range wetting phenomena and long-range van-der-Waals interactions.
520 $a Finally, the particle-based approach is extended to a dynamic study with shear. Bond length and mean-square displacement are investigated, and shear's effect on phase behavior is dismissed.
