Abstract:
Molecular dynamics ( MD) simulations are carried out with Born-Mayer-Huggins and Lennard-Jones interaction potentials. We investigate the motion characteristics of KI nanoparticles attached on the outside of carbon nanotubes ( CNTs) with temperature gradient ( T) . The results demonstrate that there are two kinds of motion modes during KI nanoparticles move from the hot zone to the cold zone of the CNTs. Through the analysis of the trajectory of KI nanoparticles supported on the CNTs subject to temperature gradient,we find the shape of the moving route are affected by the chirality,diameter,and temperature gradient of CNT. The analysis of the force added on KI nanoparticles supported on the CNTs with temperature gradient can account for the relationship between the motion modes of KI nanoparticles and the chirality of CNT. The results of this article may be instructive in designing of novel nanoscale motors.
