摘要:
利用经典分子动力学方法,计算分析了单壁碳纳米管、双壁碳纳米管的扭转力学行为,结果表明,相同口径的双壁碳管,在长度一致的情况下,其扭转刚度与碳管结构关联很小.以锯齿型管为外壁的双壁管扭转时的轴向力使碳管伸长,而以其他类型管为外壁的双壁碳管扭转时轴向力使碳管收缩.这些结果对相关纳米器件的设计有重要意义.
Abstract:
We calculate and analyze the torsional mechanical behavior of single-walled and double-walled carbon nanotubes using classical molecular dynamics． It is found that the torsional stiffness is nearly independent of their structures for double-walled carbon nanotubes( DWCNTs) with same diameter and length． However， if outer tube of the DWCNT is zigzag-type， its axial stress will extend the DWCNT，whereas other type of outer tube will shrink the DWCNT． These results are very important for designing of the nano-electro-mechanical systems( NEMS) ．
