Aramid fibers are a class of heat-resistant and strong synthetic fibers. They are used in aerospace, military, and technical applications. In comparison with p-Aramid, m-Aramid can be easily manufactured into fibers and films via solution processe. Multi-walled carbon nanotube (MWCNT) has been considered as the ideal reinforcing nanoscale filler for polymeric material owing to its high aspect ratio, mechanical property, thermal stability and electrical conductivity. Electrospinning is a process to make fine fibers from a polymer solution or melt by using an electrical charge. In this study, we have prepared a series of m-Aramid/MWCNT composite nanofibers via electrospinning method. Morphological and structural features of m-Aramid/MWCNT composite nanofibers are characterized by using SEM, TEM, and XRD. Thermal stability, mechanical performance, and electrical conductivity of m-Aramid/MWCNT composite nanofibers are also investigated with aides of TGA, DMA and electrometer, respectively. |
