Outline of Final Research Achievements

Soft matter such as polymers and liquid crystals has microscopic structures, which interplay with flow. We have investigated the effect of the structure on the rheological properties related to shear flow by applying microrheology. First, we observed both orientation and shear flow fluctuations at equilibrium to obtain the cross-correlation function between them, and elucidated the existence of interplay. Furthermore, we compared the experiment with a theoretical result derived from the Ericksen-Leslie Theory. Next, we observed sheared particles dispersed in a xthantan solution and found an anomalous diffusion due to the molecular interaction.
