Outline of Final Research Achievements

We studied anisotropic gelation phenomena by the liquid-liquid contact such as dialysis by paying attention to the thermo-statistical-mechanical properties of the sol solution near the sol-gel interface (sol solution on the interface). The Monte-Carlo simulation we performed shows that the anisotropy of the gel is induced by the chemical potential gradient and the constraint imposed on the polymer chain motion by the sol-gel interface. We constructed the dynamics changing from the sol solution on the interface to the anisotropic gel based on the Allen-Cahn-type phase-transition dynamics. By means of the newly-derived dynamics and the moving-boundary picture, we analyzed several anisotropic gelation phenomena and considered blood coagulation from a view point of the gelation phenomena induced by the liquid-liquid contact.
