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.
