Revealing the anomalous tensile properties of WS2 nanotubes by in situ transmission electron microscopy
Abstract
Mechanical properties and fracture behaviors of multiwalled WS<sub>2</sub> nanotubes produced by large scale fluidized bed method were investigated under uniaxial tension using in situ transmission electron microscopy probing; these were directly correlated to the nanotube atomic structures. The tubes with the average outer diameter approximately 40 nm sustained tensile force of approximately 2949 nN and revealed fracture strength of approximately 11.8 GPa. Surprisingly, these rather thick WS<sub>2</sub> nanotubes could bear much higher loadings than the thin WS<sub>2</sub> nanotubes with almost "defect-free" structures studied previously. In addition, the fracture strength of the "thick" nanotubes did not show common size dependent degradation when the tube diameters increased from approximately 20 to approximately 60 nm. HRTEM characterizations and real time observations revealed that the anomalous tensile properties are related to the intershell cross-linking and geometric constraints from the inverted cone-shaped tube cap structures, which resulted in the multishell loading and fracturing.
