Multi-Scale Study of Tensile Mechanical Properties of Carbon Nanotube Film under Lateral Loading

In this paper, tensile mechanical properties of carbon nanotube (CNT) film under lateral loading are measured. Comparing with works before, it is found that elastic modulus of CNT film under lateral stretch is higher than that under longitudinal stretch, which is an interesting experimental result. With multi-scale experimental methods including SEM and micro-Raman spectroscopy, the change of CNT bundle network of the film under lateral stretch and axial elongation of CNTs in the loading direction are measured. Based on the experimental results, the control mechanism on difference of lateral and longitudinal mechanical properties of CNT film is analyzed.

Carbon Nanotube Fibers

This paper presents an experimental study on the tensile mechanical properties of carbon nanotube (CNT) fibers by in situ Raman spectroscopy. The comprehensive spectral information, such as Raman shift, width and intensity, are recorded during the whole loading–unloading–reloading procedures of CNT fibers. Based on the experimental results, the elastic-plastic deformation evolution of CNT fibers are analyzed at multi-scale levels. It is found that the elastic deformation of the fiber is mainly attributable to the elastic stretching of the CNTs inside the bundles. And the plastic deformation is caused mainly by the slippages at the interfaces among CNTs inside the bundles. Meanwhile, the CNTs deform elastically during the whole loading–unloading–reloading procedures.
