Fig. 2. Average fiber diameters and inter-fiber distances of the PCL, PVA, PPCS, and PPCS-SDF1 membranes. Average fiber diameters of the PCL, PVA, PPCS, and PPCS-SDF1 membranes (A). Average inter-fiber distances of the PCL, PVA, and PPCL membranes (B). (*) indicates p-values where a statistically significant difference (p ≤ 0.05) is observed. NS indicates no statistically significant difference.
