Abstract: We present classical molecular dynamics simulations demonstrating that single-wall carbon nanotube (SWNT) bundles collapse under hydrostatic pressure. The collapse pressures obtained as a function of nanotube diameter are in excellent quantitative agreement with new data presented here for small diameter (d approximately 0.8 nm) SWNTs, and the majority of previously published results, although there remain some unreconciled contradictions in the literature. The collapse pressure is found to be independent of t… Show more

“…The transition or collapse pressure varied with the symmetry, chirality, and diameter of the CNTs [29,59,64,[66][67][68][69]. Usually, the larger the diameters of CNT bundles are, the lower the transition pressure will be [29,59,64,[66][67][68][69].…”

“…This result implies that larger diameter SWCNTs could yield stiffer fibers of low density-the density of SWCNTs scales inversely with their diameter. Interestingly, recent experimental results show that large-diameter single and double-walled carbon nanotubes yield fibers with the best mechanical properties achieved so far (30, 31)-although there are limitations, because excessively large few-walled carbon nanotubes are prone to buckle radially into flattened ribbons (32,33). Because stiffness is an important property in biological systems, the diameter-dependent rigidity of SWCNTs should also be considered as a potentially important variable in studies of interactions of carbon nanotubes with cells.…”

“…The CNT efficiency parameters are given in Table 1. As the material properties of SWCNTs are chirality, size and temperature-dependent [40][41][42][43], typical values are taken from the analytical results of Popov et al [44]. The dimensionless deflection and load used in this paper are defined as…”
