Description
Summary:The possibility of strain engineering of friction in carbon nanotube is explored in this paper. The intertube friction in double-walled carbon nanotube under torsional strain is calculated by employing the molecular dynamics simulations. By studying the intertube friction in double-walled carbon nanotube subjected to torsional strain, it is found that the friction can be tuned by torsional strain. It shows that the temperature has great influence on torsional strain effects on intertube friction. Mechanism and physical insight of torsional strain effects are revealed by numerical and phonon spectra analysis. It is found that the torsional strain accelerates of the exchange from order kinetic energy to disorder thermal energy. The work in this paper implies the potential of strain engineering in nanoscale friction and brings new insight into fundamental understanding of strain-effect mechanism in nanoscale friction.
