Abstract

Carbon nanotube (CNT) has excellent mechanical, electrical, and thermal properties, and is anticipated to be used in various fields such as chemical sensors and nanoelectronic devices and for reinforcing nanofillers. Due to its highly cohesive properties, however, it is difficult to make the most of the characteristics of CNT. Recently, the electrospinning method has attracted attention as a method of dispersing CNT. In this study, CNT/polyamide 6 (PA6) composite nanofibers were fabricated by an electrospinning process, and the dispersion of CNT in nanofibers was evaluated. To disperse CNT in CNT/PA6 nanofibers for the electrospinning process, acid treatment was applied to CNT. CNT/PA6 films were made of CNT/polyamide 6 (PA6) composite nanofibers, and their tensile strength was evaluated. The dispersion of treated CNT in the nanofiber was higher than that of untreated CNT. The tensile strength of treated CNT/PA6 film is higher than that of untreated CNT/PA6, and they are both higher than that of PA6 film.
