Effect of Co-polyester antistatic agent modified by carbon nanotubes on the properties of polypropylene fibers

Antistatic polymer fibers were investigated by using carbon nanotubes （CNTs） to enhance the antistatic ability of inner antistatic agents based on the mechanism of attracting moisture by polar radical groups. It is indicated that the antistatic ability of the fibers filled with composite antistatic agents that contain CNTs and organic antistatic agents was superior to that of the fibers filled either with pure organic antistatic agents or pure CNTs. The antistatic ability of the composite antistatic agent fabricated by an in situ process was superior to that of the composite antistatic agent fabricated by direct dispersing CNTs in the antistatic agent carrier. Moreover, the heat-treated CNTs could further enhance the antistatic effect compared with the initial CNTs. The antistatic effect is significantly influenced by the content of CNTs in the composite antistatic agent.

An antistatic agent based on polyionic liquid applied to nylon 6

In order to improve the electrical conductivity of nylon 6(PA6)and avoid misfires and explosions caused by static charge accumulation,a quaternary ammonium salt polyionic liquid(PIL)antistatic agent was synthesized in this paper.The surface resistance of PA6 was reduced to 10~8Ωwith the addition of 2 wt%antistatic agent,and the mechanical properties and aging resistance of the substrate were improved.Meanwhile,the morphology and crystallinity of PIL/PA6 composites were further characterized by scanning electron microscope(SEM),energy dispersion spectrometer(EDS)and X-ray diffraction(XRD).It is worth noting that the quaternary ammonium salt polyionic liquid antistatic agent synthesized in this paper has the advantages of excellent antistatic effect,durability,low cost,and simple reaction condition,so it has a broad application prospect in the antistatic aspect of PA6.
