Effects of different concentrations of EL and ES on the diameter of blank NFs

Polymer concentration (%)	EL-NF diameter (nm) ± SD	ES-NF diameter (nm) ± SD
10	51.2d±22.7	69.7d±24.8
15	124.4c±50.3	171.4c±37.2
20	295.2b±91.2	590.4b±156.2
25	355.7a±117.2	864.4a±371.8

Notes: The feeding rate was 0.5 mL/h at an applied voltage of 15 kV. a > b > c > d.

Abbreviations: EL, Eudragit L100; ES, Eudragit S100; NF, nanofiber; SD, standard deviation.
