Axial Young’s modulus prediction of single-walled carbon nanotube arrays with diameters from nanometer to meter scales Available to Purchase

Based on a self-similar array model, we systematically investigated the axial Young’s modulus $(Yaxis)$ of single-walled carbon nanotube (SWNT) arrays with diameters from nanometer to meter scales by an analytical approach. The results show that the $Yaxis$ of SWNT arrays decreases dramatically with the increases of their hierarchy number $(s)$ and is not sensitive to the specific size and constitution when $s$ is the same, and the specific Young’s modulus $Yaxiss$ is independent of the packing configuration of SWNTs. Our calculations also show that the $Yaxis$ of SWNT arrays with diameters of several micrometers is close to that of commercial high performance carbon fibers (CFs), but the $Yaxiss$ of SWNT arrays is much better than that of high performance CFs.
