Abstract
AbstractIn this study, nylon‐6 nanofiber mats containing Fe2+ ions were fabricated via electrospinning. The resultant electrospun nylon‐6/FeCl2 nanofiber mats were characterized by SEM, TEM, Fourier transform IR spectroscopy, wide angle XRD and DSC. Unique morphological features, such as spider's‐web‐like morphologies, were observed and became evident with increasing additive Fe2+ ions. The metastable γ form was predominant in the as‐spun nylon‐6 nanofibers. The relative intensity of such γ form gradually decreased with increasing additive Fe2+ ions, indicative of transformation of the crystalline structure in the electrospun nylon‐6/FeCl2 nanofibers due to strong molecular interactions between the nylon‐6 backbone and the additive Fe2+ ions. The effects of additive Fe2+ ions on the mechanical properties of both nonwoven nanofiber mats and single nanofibers were investigated. In particular, Young's modulus of nylon‐6/FeCl2 single nanofibers gradually increased from 1.46 to 5.26 GPa with increasing additive Fe2+ ions. © 2013 Society of Chemical Industry
