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.
