statistical characterization of single wall carbon nanotube length distribution
Nanotechnology, 2006Co-Authors: Shiren Wang, Zhiyong Liang, Ben Wang, Chuck ZhangAbstract:This paper describes an effective method for quantifying the length and length distribution of large populations of single-wall carbon nanotubes using atomic force microscopy and SIMAGIS software. The results of the measurements were modelled with the Weibull distribution, resulting in a statistically confirmed fit. The fitted Weibull distribution was used to predict the length effect factor and elastic modulus as functions of nanotube pRoperties in composite materials. The prediction shows that the length factor for the elastic modulus tends to increase with enhanced loading but decrease with rising Rope Diameter. The statistical characterization presented indicates a pathway for the future theoretical modelling and related experimental investigation of carbon nanotube application.

Rings and rackets from single-wall carbon nanotubes: manifestations of mesoscale mechanics
Soft Matter, 2014Co-Authors: Yuezhou Wang, Matthew R. Semler, Igor Ostanin, Erik K. Hobbie, Traian DumitricăAbstract:We combine experiments and distinct element method simulations to understand the stability of rings and rackets formed by single-walled carbon nanotubes assembled into Ropes. Bending remains a soft deformation mode in Ropes because intra-Rope sliding of the constituent nanotubes occurs with ease. Our simulations indicate that the formation of these aggregates can be attributed to the mesoscopic mechanics of entangled nanotubes and to the sliding at the contacts. Starting from the single-walled carbon nanotubes, the sizes of the rings and rackets' heads increase with the Rope Diameter, indicating that the stability of the experimental aggregates can be largely explained by the competition between bending and van der Waals adhesion energies. Our results and simulation method should be useful for understanding nanoscale fibers in general.
