Spinline behavior and web morphology in multi-nozzle electrospinning of PAN/DMF solution

The spinline behavior, the web morphology and the crystallinity in multi-nozzle electrospinning were investigated using photography, SEM and XRD. It was found that the spinlines of each nozzle had skewed bell shapes and changed along the nozzle alignment and location. The alignment of the nozzles showed significant effects on both the spinline shape and the fiber web morphology. The fiber diameter and the crystallinity were changed along the collected position. They were resulted from the balance of the self-induced and the mutual Coulombic interactions of the spinlines.
