摘要：

A discussion about the shear and Young's moduli measurements of MoS2 nanotube ropes was presented. A nano-beam configuration in which ropes of MoS2 were dispersed on the surface of a porous membrane was used. An atomic force microscope (AFM) was engaged to elastically deform the ropes and the value of bending modulus was measured for an ensemble of tubes. From the measurements, the lower estimate of Young's modulus of MoS2 tubes was extrapolated as 120GPa and the value of the inter-tube shear modulus was found to be 160±30 MPa, which indicated that MoS2 ropes are highly anisotropic.
