FIGURE 3 The SEM images and fiber diameter distributions of electrospun fibers in solution
concentration of (a) 10 wt.%, (b) 12 wt.%, and (c) 14 wt.%.
Figure 5 represents the SEM image and fi ber diameter distribution of electrospun
nanofi bers in different spinning distance. It can be seen that the AFD decreased with
increasing tip to collector distance. Because of the longer spinning distance could give
