| Abstract: | Crbon nanotubes(CNTs)/Lyocell composite fibers were prepared by using single-walled carbon nanotubes(SWNTs) and multi-walled carbon nanotubes(MWNTs),as the additives,respectively.The effects of the kinds of CNTs on the structure and properties of CNTs/Lyocell composite fibers were investigated.The results show that the kind of CNTs has no influence on the crystal structure,and 1% SWNTs or MWNTs can be dispersed uniformly in the matrix.Moreover,the thermal properties of CNTs/Lyocell composite fibers can be improved by the addition SWNTs or MWNTs,wherein SWNTs is more effective than MWNTs.The addition of appropriate amount of CNTs can also improve the mechanical properties of composite fibers,the tensile strength and initial modulus of the composite fibers with 1% SWNTs(MWNTs) were increased by 24.2%(18.8%) and 55.8%(47.9%),respectively,compared with the pure Lyocell fiber.In addition,the SWNTs/Lyocell composite fibers have better electrical properties than MWNTs/Lyocell fibers. |
