采用静电纺丝法制备太极石母粒/PET复合纤维,探讨了太极石纳米颗粒含量对太极石母粒/PET复合纤维的形态结构、结晶性能、力学性能和热稳定性能的影响。试验结果表明:添加少量的太极石母粒能够使纳米颗粒均匀地分散在复合纤维中;太极石母粒中的纳米颗粒并没有明显改变PET的分子结构和化学组成;由于纳米颗粒阻碍了基体大分子链的移动和晶体的形成,使复合纤维的结晶度有所下降;太极石母粒的加入明显提高了复合纤维的热稳定性能;少量的太极石纳米颗粒能够改善复合纤维的力学性能,但随着太极石纳米颗粒的继续增加,复合纤维的力学性能有所降低。
The electrospinning method was used to prepare the Taizi Masterbatch / PET composite fiber. The effects of the content of Taizi Nanoparticles on the morphology, crystallinity, mechanical properties and thermal stability of the Taiji masterbatch / PET composite fiber were discussed. The experimental results show that the addition of a small amount of Ta Ji masterbatch can disperse the nanoparticles uniformly in the composite fibers. The nanoparticles in the Taiji masterbatch do not significantly change the molecular structure and chemical composition of the PET. Due to the nano-particles hindering the growth of the matrix The molecular chain movement and crystal formation led to the decrease of the crystallinity of the composite fibers. The addition of tungstones significantly enhanced the thermal stability of the composite fibers. A small amount of tantalum nanoparticles could improve the mechanical properties of the composite fibers. However, The mechanical properties of the composite fibers decreased with the continuous increase of the tantalum nanoparticle.
