Hydrodynamic Behavior of Carbon Nanotubes and Characterization of Length Distributions



Carlos A. Silvera Batista, Ming Zheng, Constantine Y. Khripin, Xiaomin X. Tu, Jeffrey Fagan


The sedimentation behavior of SWCNTs was studied through analytical ultracentrifugation. SWCNTs were dispersed with the aid of surfactants, doubly sorted by density and length to produce samples with invariant diameter distributions and aspect ratios that vary by an order of magnitude. Sedimentation velocity experiments on samples of narrow length distributions thus served to validate expressions for the friction coefficients of rigid rods. As a proof of concept, it was also possible to calculate particle length distributions from the measured sedimentation coefficient distributions.
