摘要：On the basis of the atomistic simulations of electrowetting in single-walled carbon nanotubes, electrowetting Of double-walled carbon nanotubes by mercury is studied Using Classical molecular dynamics simulations. Wetting of double-walled carbon nanotubes by Mercury Occurs above a threshold size of inner tube when the voltage is applied on the outer tube, but no wetting phenomenon appears when the voltage is applied on the inner tube. The filling rate increases greatly with enlarging the inner tube size. The space between the two walls of double-walled carbon nanotubes cannot be filled by mercury during electrowetting process.
