| Research Abstract |
In order to study inhomogeneous polymeric systems, we developed multi-scale theories ranging from microscopic monomeric scales to macroscopic hydrodynamic scales. Our main methodology is the density functional theory with which one can describe polymer systems on the coarse-grained level. By extending this theory to dynamical phenomena, we studied structure formation and structural transition of phase separated polymer systems under an external electric field or a flow field. We also developed a hybrid approaches by combining this density functional theory with molecular models or by combining it with membrane models, and studied their behavior by computer simulations.
