Figure 7.

(A) Correlation between the shape of the jet and the speed of the collector (SC) relative to the speed of the jet (SJ) during melt electrospinning. (B) Photograph of PCL fibers produced by melt electrospinning. The collector was moving at constant horizontal speeds that increase from the top to the bottom as indicated on the images. (C and D) SEM images showing the assembly of PCL fibers into multilayered stacks with the orientation of fibers in adjacent layers rotated by 90° and 60°, respectively.
