Bicomponent melt spinning of polyamide 6/carbon nanotube/carbon black filaments: Investigation of effect of melt mass-flow rate on electrical conductivity

Combining the several mixed phase structures and property profiles with a conductive, high aspect ratios nanofiller such as carbon nanotubes, graphene, black, specific morphological in melt spinning can be reached that offer much more potential for developing new functional fibers. Thus, understanding controlling filler localization inside morphology during are keys to necessary structures. This work aimed possibility of producing fibers from electrically conductive polymer composites concentration. First, influence different commercially available nanofillers, multi-wall nanotubes (MWCNTs), graphene black on Polyamide 6 (PA6)-based nanocomposite melt-spun were examined. Following lab-scale experiments, PA6/MWCNT-CB filaments containing 10 wt% (each 5 wt%), chosen pilot-scale bicomponent process investigate core material feeding parameters properties The electrical conductivity decreased by half (from 3.13E-02 6.72E-03) when flow rate was increased 3 g/min g/min. Scanning electron microscopy micrographs thermal gravimetric analysis thermograms showed change MFR values significantly affected filaments’ surface properties.
