摘要: Abstract The versatile electrospinning technique was used to successfully align and disperse multiwalled carbon nanotubes (MWCNT) in nylon 6,6 matrix obtain composite fibers. morphology of the fibers dispersion CNTs within were analyzed using scanning electron microscopy (SEM) transmission (TEM), respectively. TEM analysis revealed that well-dispersed, separated aligned along fiber axis. thermal mechanical properties characterized as a function weight fraction CNTs. Incorporation resulted an increase glass-transition temperature (Tg) by ∼7 °C, indicating addition has restricted mobility polymer chains provided confinement neighboring molecular chains. Tensile nanoindentation experiments performed investigate deformation behavior results suggested incorporation high strength aspect ratio into enhanced significantly stiffness An understanding structure–property relationships can provide fruitful insights develop electrospun with superior for miniaturized load-bearing applications.
