The Effect of Temperature and Solvent Concentration on the Nanomotor Motion by Molecular Dynamics Simulation

Abstract:

Nanomotors are nanoscale devices capable of converting energy into movement and forces. In this work, a molecular dynamic model based on a chemically powered nanomotor is established. Based on molecular dynamics, dynamics and kinematics analysis have been made, and the motion of the model has been simulated. Finally, we get the effect of the temperature and the solvent concentration on the nanomotor motion respectively. The center-of-mass velocity of the nanomotor along its axis increases roughly linearly with low temperature, and then gradually reaches a maximum value. The center-of-mass velocity of the nanomotor along its axis increases roughly linearly with low solvent concentration, and then gradually reaches a maximum value.
