Abstract:

In order to improve the mechanical properties of polyamide 66 (PA66) fiber, carboxylated multi-walled carbon nanotubes (CMWNTs) were condensed with ethylenediamine (EA) to obtain amino-functionalized multi-walled carbon nanotubes (AMWNTs), and AMWNTs doped PA66 composites (PACNTs) were prepared by in-situ polymerizing AMWNTs with polyamide 66 salt. Furthermore, the composites were melt-spun into fibers. The fibers were characterized using thermogravimetry, differential scanning calorimeter, X-ray diffraction and single fiber strength tester. The results show that, the melting temperature of the PACNTs fiber moves toward the low temperature direction as the content of AMWNTs increases, the addition of AMWNTs lowers the molecular weight of PA66, and the crystallization temperature of the PACNTs fiber moves toward the high temperature direction as a result of AMWNTs acting as a heterogeneous nucleation agent. The tensile strength and elastic modulus of the PACNTs fiber increase with increasing the content of AMWNTs. The tensile strength and elastic modulus of PACNTs fiber reach the maximum when the mass fraction of AMWNTs is 0.5%, which increase by approximately 157% and 455% as compared with those of PA66, respectively.
