Effect of Thermal Treatments on Structures and Mechanical Properties of Multi-walled Carbon Nanotube Fibers

摘要：

　　In this study, the structural changes, mechanical and electrical properties of carbon nanotube (CNT) fibers after thermal treatments in air have been investigated.The tensile strength of the CNT fibers improves about 50% after heat treatment at 250 ℃, due to the increase in crystallinity and oxygen-containing groups.In addition, Raman spectroscopy, Fourier transform infrared spectroscopy, transmission electron microscopy and field emission scanning electron microscopy are conducted to observe the structural changes of CNT fibers before and after thermal treatments.
