Abstract

Chemical post-treatment of the carbon nanotube fiber (CNTF) was carried out via intramolecular cross-dehydrogenative coupling (ICDC) with FeCl₃ at room temperature. The Raman intensity ratio of the G band to the D band (I_G/I_D ratio) of CNT fiber increased from 2.3 to 4.6 after ICDC reaction. From the XPS measurements, the A_Cî-C/A _C-C ratio of the CNT fiber increased from 3.6 to 4.8. It is of keen interest that both the electrical conductivity and tensile strength of CNT yarn improved to 3.5 × 10³ S/cm and 420 MPa, which is 180 and 200% higher than that of neat CNT yarn.
