本文研究了双壁碳纳米管（DWCNTs）的壁间摩擦和滑动行为。壁间摩擦力与内壁的拔出速度呈线性关系。多壁碳纳米管的轴向弯曲导致壁间摩擦力的显著增加。轴向曲率也影响内壁的滑动行为。与轴向曲率相比，开口端对壁间摩擦的影响较小。
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.
