Studies of block copolymer melts by field theory and molecular simulation

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.
