Autor: Shuo Bai, Aïssa Allaoui, Jinbo Bai

Publikováno v: International Journal of Nanoscience
International Journal of Nanoscience, World Scientific Publishing, 2010, 9 (1-2), pp.69-73

Carbon nanotube (CNT) yarns were drawn from the web found on the CVD furnace wall. The yarns were twisted and their tensile behavior was investigated through in-situ SEM and regular tensile tests. The mechanisms involved in the CNT yarn deformation w

Scripta Materialia, Elsevier, 2009, 61, pp.628-631. ⟨10.1016/j.scriptamat.2009.05.045⟩

International audience; We proposed to evaluate the contact resistance between carbon nanotubes from bulk measurement on their tangle. Compression tests with simultaneous measurement of the ohmic resistance were performed on carbon nanotube tangles.
