| Summary: | 碩士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 93 === We employ both self-consistent mean-field (SCMF) theory and dissipative particle dynamics (DPD) to study the phase behavior and analyze the microstructural size for a block copolymer in the presence of two solvents. In particular, the effects and the ratio between these two solvents, and copolymer volume fraction are examined. We observe that with increasing the incompatibility between the solvents, various ordered microstructures and/or two macrophase separations are expected. In further, the microstrutural size increases significantly when the systems approach the 2-phase region.
