CNTs are promising materials as nanodevices because of their excellent mechanical properties. However, on the nanoscale, nanodevices are subject to fracture due to frictional forces because of the enhanced surface effect. To solve these problems, it is necessary to study mechanics of CNTs on the nanoscale. In this work, double-wall CNT (DWCNT) is discussed in order to elucidate the mechanical properties of CNTs on the nanoscale by mechanics simulation for rotation of the inner tubes. The interaction energy of the DWCNTs showed a periodicity of about 17° with respect to the rotation angle of the inner-layer CNT. The simulated results can be explained by the periodicity of the geometry and lattice stacking of DWCNT for the rotation of the inner-layer CNT.
