| 研究実績の概要 |
The candidate has managed to performe an extensive characterisation of polymer and rod-like colloids in shear and extension in Newtonian solvents. The main output of the research is that the polymer and rod-like colloid dynamics in shear and extensions are different and strongly depends on their flexibility. Another important output of the research regards the onset of aliment of rod-like colloids in crowded polymer solutions. We find that the polymer dynamics govern the onset of shear-induced alignment of colloidal rods suspended in polymer solutions, and the control parameter for the alignment of rods is the Weissenberg number, quantifying the elastic response of the polymer to an imposed flow.
