Table 1. Electrospinning Conditions and Fiber Morphology for PVA and the Blend PVA/BSA.

feed solution	voltage (kV)	feed rate (mL/h)	tip-collector distance (cm)	note on sample morphology
10 wt % PVA	12–24	0.1–0.4	18–25	highly beaded and defective fibers
12 wt % PVA	15–21	0.05–0.1	20–30	defect-free fibers and very few beaded fibers
14 wt % PVA	15–18	0.05–0.2	25–28	homogeneous and defect-free fibers
15 wt % PVA	15–19	0.1–0.3	12–18	homogeneous and defect-free fibers
16 wt % PVA	15–17	0.2	13–18	few defect-free fibers; low production yield
12 wt % PVA (10–100)% BSA	17–19	0.3	18	homogeneous and defect-free fibers
13 wt % PVA (10–100)% BSA	17–19	0.3	18	homogeneous and defect-free fibers
14 wt % PVA (10–100)% BSA	17–19	0.3	18	homogeneous and defect-free fibers
