Optical Anisotropy of Sheared Carbon-Nanotube Suspensions



D J. Fry, B Langhorst, H W. Kim, E A. Grulke, Haonan Wang, Erik K. Hobbie


We measure the anisotropy of sheared carbon nanotube suspensions for a range of concentration, aspect ratio, and strain rate using a variety of methods. Our measurements highlight the importance of hydrodynamic interactions, with scaling over a broad range of dimensionless shear rate. Our results also suggest that hydrodynamic interactions might be exploited to fractionate carbonnanotubes by length.
