TLDR
Here, the interwall friction and sliding behaviors of double-walled carbon nanotubes (DWCNTs) are studied to show a linear dependence on the pullout velocity of the inner wall and the axial curvature causes the significant increase of the inter wall friction.Abstract:
Here, we studied the interwall friction and sliding behaviors of double-walled carbon nanotubes (DWCNTs). The interwall friction shows a linear dependence on the pullout velocity of the inner wall. The axial curvature in DWCNTs causes the significant increase of the interwall friction. The axial curvature also affects the sliding behavior of the inner wall. Compared with the axial curvature, the opening ends of DWCNTs play tiny roles in their interwall friction.read more
