| Abstract: | A series of CMWNTs/PA66 composite fibers were melt-spun with the melt-blended PA66 and 0.1 wt%~3 wt% of carboxylic multi-walled carbon nanotubes chips.The effects of CMWNTs mass fraction on the morphology and mechanical properties of the composite fibers were characterized using SEM,DMA and a tensile strength tester etc.The results show that the CMWNTs are homogeneously dispersed throughout PA66 matrix.Both the Tg and mechanical properties of the composite fiber increase due to the addition of CMWNTs.When t... |
