Research Abstract

The target of this research project is to reveal dynamics of morphology transitions in complex liquids (soft matter). For this purpose we investigated the following three systems.
1. Order-order transition of surfactant/water systems and block copolymers.
Characteristic fluctuation modes are observed prior to an order-order transition. Which brings the destination ordered phase through a meta stable intermediate phase. This behavior is well described by the Gintzburg-Landau scheme. Furthermore we developed a mode expansion theory, which reveals the kinetic pathway of the order-order transition.
2. Morphology transition of rod partical + polymer system.
Addition of polymer to the rod particle suspension brings isotropic to nematic transition. This phenomenon is induced by compentition between translational entropy and mixing entropy(depletion interaction). We found that the semi-rigid polymer enhances the depletion interaction extensively (^~10^<3-4>) due to the large excluded volume effect.The Monte-Carlo simulation reproduces the observed phenomenon as a function of the chain rigidity.
3. Morphology transition of membrane + polymer system.
Using microemulsion droplet phase, we can confine polymer chains into a nano-scale closed spherical container. The entropy loss of the polymer chain due to the confinement brings morphology transition in order to minimize the total free energy consisting of conformational entropy of the chain and elastic energy of the membrane.
