The influence of NaOH concentration upon wetting and wicking parameters. The porosity (A) of the post-treated nanofibers was not significantly affected by the NaOH concentration. The water contact angle shows a significant reduction at NaOH concentration lower than 0.25 M (B); The wicking time of liquid from sample pad to test line of NaOH-treated electrospun PCL nanofibers substantially reduced as the NaOH concentration increased at 0.25 M (C). n = 4 for each concentration in (A,B), and n = 3 for each concentration in (C). * represents p < 0.05.
