Fiber morphology and diameter distribution for 8 wt% PLA solution spun at different rotation speeds, Spun at (a) 4,000 rpm, (b) 8,000 rpm. (c) 12,000 rpm, scale bar is 10µm. (d) Diameter distribution of all samples in box plots, the horizontal lines inside the boxes represent the median values and the limits of the box denote the upper and lower quartiles. The maximum and minimum values delimit the bars. (e) Diameter distribution of PLA samples at different polymer concentration spun at 12,000 rpm.
