  Abstract

To improve the electrical conductivity of the carbon nanotube (CNT) fibers produced by the continuous spinning method, conductive materials such as silver nanoparticles, gold nanoparticles, and silver nanowires were added. The structures of the CNT fiber/conductive materials composites were observed using scanning electron microscopy. Raman spectroscopy was used for identifying the possible damages to the CNT fiber during the process of adding the conductive materials. Electrical conductivities of the CNT fiber/conductive materials composites were measured by the four-probe method. The Raman spectroscopic results indicated that there was no significant damage in the CNT fibers of the CNT fiber/conductive materials composites. The electrical conductivity of the CNT fibers increased up to 54% after the addition of the conductive materials.
