ELECTROSPINNING POLY(Ε-CAPROLACTONE) UNDER CONTROLLED ENVIRONMENTAL CONDITIONS
Figure 2.3 PCL fibers electrospun from solution 15 wt% in CHCl3, at 20°C and 50% relative humidity for 5 minutes. The degree of orientation changes by increasing the uptake speed; totally random non- woven at 1.0 m/s (a), incipient alignment at 1.6 m/s (b), oriented fibers at 1.7 m/s (c), monolayers of fibers at 1.8 m/s (d). The corresponding FFT output images are shown in (e), (f), (g) and (h) and the plotted pixel intensity [a.u.] vs. angle are in (i), (j), (k) and (l).
