发布时间：2019-06-19 03:09
【摘要】：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。
[Abstract]:Several kinds of nanopin based on branch carbon nanotube (CNT) were simulated by classical molecular dynamics (MD) method, and the two installation methods were compared. the installation feasibility of double branch tube nanopin and the effect of control end length on the installation performance of double branch tube nanopin were studied in detail. The results show that, compared with push installation, pull installation not only advances the installation of its branch pipe, but also increases the maximum installation resistance in the installation process by an order of magnitude, so the push installation is more practical. The double branch tube nanopin can be successfully installed, but the slight bending of the nanopin caused by the joint of the branch tube requires more strict screening and positioning error correction. The length of the control end and the position of the second branch pipe of 20 nm do not directly cause the flexion of the nanopin head of the double branch tube. Therefore, the installation accuracy of nanodevices and the effective connection of nanocomponents can be realized, while the installation of nanopins with more branches needs to be further explored and optimized.
