采用经典分子动力学(MD)方法对几种基于分支结构碳纳米管(CNT)的纳米销进行安装过程模拟,比较了两种安装方式,重点研究了双支管纳米销的安装可行性及控制端长度对双支管纳米销安装性能的影响。研究表明:相比于推安装,拉安装不仅将其支管的安装提前了,也将安装过程中的最大安装阻力提升了一个量级,因此推安装更加实用;双支管纳米销可以被成功安装,但具有更多支管的纳米销由于支管关节引起的主管轻微弯曲需要更严格的筛选和定位误差修正;20 nm的控制端长度和第二支管位置并不会直接造成双支管纳米销主管的屈曲。因此,双分支结构碳纳米管可以实现纳米器件的安装准确性和纳米构件的有效连接,而具有更多支管的纳米销的安装则需要进一步探索和优化。
Several kinds of nanotubes based on branching carbon nanotubes (CNTs) were simulated by classical molecular dynamics (MD) method. Two kinds of mounting methods were compared. The feasibility of installation of the double-branch nanotubes and the control end Effect of length on the installation performance of double branch tube. The study shows that pulling installation not only advances the installation of its branch pipe but also increases the maximum installation resistance during installation by one order of magnitude compared with the push installation, so the push installation is more practical. The double branch pipe nano pin can be successfully installed, However, nanotube pins with more branches require more rigorous screening and positioning error correction due to slight buckling of the supervisor due to the branch joints; the control end length of 20 nm and the second branch position do not directly cause buckling of the double-branch nanotube pin. Therefore, the bifurcated carbon nanotubes can achieve the mounting accuracy of nano-devices and the effective connection of nano-components. The installation of nano-pins with more branches needs to be further explored and optimized.
