ABSTRACT
This chapter provides a review of the studies about composite fibers produced by using carbon nanotubes, silver nanoparticles, and polyaniline and shows that it is possible to produce functional fibers/filaments with the incorporation of the additives into fiber/filament structure. Carbon nanotubes are widely added to fiber structure to improve mainly the mechanical properties and electrical properties, besides thermal properties, thermal stability. The use of carbon nanotube in filament reinforcement is of particular interest since the stresses applied during fiber spinning contributes to the alignment of the carbon nanotubes along the fiber axis which makes it possible to better utilize the excellent properties of carbon nanotubes. Carbon nanotubes have attracted great interest both from industry and academy with their unique mechanical, thermal and electrical properties since their discovery. The high aspect ratio of the carbon nanotubes resulting in low percolation thresholds makes them outstanding conductive additives.
