A rheo-SANS study on the effect of aspect ratio and stiffness on shear-induced order in rod-like colloids
The effect of aspect ratio and flexibility on the flow behavior of colloidal rods will be studied by means of rheo-SANS. The alignment of four different monodisperse rod-like bacteriophages will be mapped by their azimuthal angle distribution as a function of shear rate using the shear cell of d22 that allows for scattering experiments in the flow-gradient plane, rendering the degree of flow-induced ordering and orientation. By using phages with varying engineered aspect ratio and stiffness, we will create a data set that can be used as a hall mark for testing theoretical predictions as well as a starting point for understanding mechanical responses of industrial systems.
