Morse and Frank S. Bates. 1 computer file (PDF); xii, 232 pages, appendices A-J. Ill. (some col.)The thesis covers theoretical and simulation studies of various phase behavior related to block copolymers and homopolymer blends. The non-frustrated triblock copolymer phase behavior is examined using the numerical SCFT (self-consistent field theory). The long ranged composition fluctuations in binary homopolymer blends and diblock copolymer melts are studied using both a renormalized fluctuating field theory and (for diblock copolymer) Monte Carlo simulations.en-USMolecular simulationPolymer phase behaviorStatistical mechanicsMaterial Science and EngineeringThesis or Dissertation
