Because of the very small structure of CNTs, the tensile strength of the tube is dependent on its weakest segment in a similar manner to a chain, where the strength of the weakest link becomes the maximum strength of the chain. Source: Internet
CNTs are not nearly as strong under compression. Source: Internet
CVD growth of CNTs can occur in vacuum or at atmospheric pressure. Source: Internet
Yu et al. citation reported on "chemically bonded graphene leaves" growing along the sidewalls of CNTs. Source: Internet
CNTs are readily aligned in a high density geometry (i. Source: Internet
Large quantities of nanotubes can be synthesized by these methods; advances in catalysis and continuous growth are making CNTs more commercially viable. Source: Internet
