我们已经研究了使用碳纳米管尖端在聚碳酸酯上制造纳米压痕的条件，所述碳纳米管尖端的结构稳定性。即使在~ 50 nN的弱力作用于纳米管的轴向方向上，平均深度为3.91 nm的压痕在室温下在空气中的聚碳酸酯上成功地实现。在这种情况下，从使用透射电子显微镜的观察来看，在51次压痕实验之后，纳米管尖端没有结构变化。这不仅可以通过使用低力条件来实现，还可以通过纳米管尖端的适当形状来实现。
We have investigated conditions for making nanoindents on a polycarbonate using a carbon nanotube tip in terms of structural stability of the nanotube tip. Even under a weak force of ~ 50 nN acting in the axial direction to the nanotube, the indents with mean depth of 3.91 nm were successfully realized on the polycarbonate in air at room temperature. In this case, there were no structural changes of the nanotube tip after 51 indentation experiments from observations using a transmission electron microscope. This could be achieved by using not only a low-force condition but also by the appropriate shape of the nanotube tip.
