Flow of silica rods in microfluidic channels — •Hansol Jeon1 and Dirk Aarts2 — 1Max Planck Institute for dynamics and self-organization, Göttingen, Germany — 2University of Oxford, Oxford, United Kingdom
This project presents the flow of dense liquid crystal phases of colloidal silica rods in microfluidic channels. We describe the synthesis of silica rods that exhibit three different phases (isotropic, nematic and smectic). Using microfluidic channels of novel designs, we observe the flow behaviour of silica rods in the channels by confocal microscopy. We then conduct image analysis to track the dyed rods and measure the flow profile. We compare the flow profiles with the theory and provide future outlook to this experiment.
