Abstract: We study the phase behavior of rod-sphere mixtures in equilibrium and under shear flow. Mixtures of fd virus, which is an established modelsystem for monodisperse colloidal rods, and density matched polystyrene beads were investigated. We used well defined size ratios L/d around 1, where L=880 nm is the length of the rod-like viruses and d diameter of the density-matched polystyrene beads. Employing Diffuse Wave Light scattering and Confocal microscopy we obtained the equilibrium phase diagram of these mixtures and identified the morphology during phase separation. we identified structure formation and distortion around the gas-liquid phase boundary with a counter-rotating shear cell mounted on the confocal microscope.
