【摘要】：采用經(jīng)典分子動(dòng)力學(xué)(MD)方法對(duì)幾種基于分支結(jié)構(gòu)碳納米管(CNT)的納米銷(xiāo)進(jìn)行安裝過(guò)程模擬,比較了兩種安裝方式,重點(diǎn)研究了雙支管納米銷(xiāo)的安裝可行性及控制端長(zhǎng)度對(duì)雙支管納米銷(xiāo)安裝性能的影響。研究表明:相比于推安裝,拉安裝不僅將其支管的安裝提前了,也將安裝過(guò)程中的最大安裝阻力提升了一個(gè)量級(jí),因此推安裝更加實(shí)用;雙支管納米銷(xiāo)可以被成功安裝,但具有更多支管的納米銷(xiāo)由于支管關(guān)節(jié)引起的主管輕微彎曲需要更嚴(yán)格的篩選和定位誤差修正;20 nm的控制端長(zhǎng)度和第二支管位置并不會(huì)直接造成雙支管納米銷(xiāo)主管的屈曲。因此,雙分支結(jié)構(gòu)碳納米管可以實(shí)現(xiàn)納米器件的安裝準(zhǔn)確性和納米構(gòu)件的有效連接,而具有更多支管的納米銷(xiāo)的安裝則需要進(jìn)一步探索和優(yōu)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.
