Limits of mechanical energy storage and structural changes in twisted carbon nanotube ropes

Abstract

Arrays of twisted carbon nanotubes and nanotube ropes are equivalent to a torsional spring capable of storing energy. The advantage of carbon nanotubes over a twisted rubber band, which is used to store energy in popular toys, is their unprecedented toughness. Using ab initio and parametrized density functional calculations, we determine the elastic range… (More)
