Figure 1: SEM images of emulsion electrospun PLGA/Chitosan/PVA nanofibrous mats ((a), (b), (c), (d), (e), and (f) are SEM images of samples numbered as 1, 2, 3, 4, 5, and 6 described in Table 1, respectively. Electrospinning parameters are voltage of 16 Kv, feed rate of 0.25 mL/h, and tip-collector distance of 15 cm).
