摘要：

We have directly measured the Young's modulus and tensile strength of multiwall carbon nanotubes by pulling very long (similar to 2 mm) aligned nanotube ropes with a specially designed stress-strain puller. This puller can apply an axial force to the rope and simultaneously measure the corresponding rope elongation and the change in rope resistance. The average Young's modulus and tensile strength obtained were 0.45+/-0.23 TPa and 1.72+/-0.64 GPa, respectively, which are lower than those calculated and measured previously. The factors that affect the mechanical strengths of nanotubes are discussed. (C) 1999 American Institute of Physics. [S0003-6951(99)05321-8].
