| Summary: | 碩士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 93 === We employ Dissipative Particle Dynamics (DPD) to simulate the phase behavior for a surfactant in the presence of two solvents. Two kinds of surfactants A1B1and A1B3 are studied. For the case of two miscible solvents, we find that the systems undergo a two macrophase separation with a surfactant-rich phase and a solvent X2/Y2-rich phase. With increasing the incompatibility between these two solvents, due to the fact that both solvents partition into their respective favored domain, ordered microphase region is enlarged.
