Medicated Nanofibers Fabricated Using NaCl Solutions as Shell Fluids in Modified Coaxial Electrospinning

Table 2

The different behaviors of working fluids under different shell fluid flow rate.

Number	Process		Taylor cone	Straight fluid jet	Instable region
F1	Single	0	Clogging	Varied	Discontinuous bending and whipping
F2	Coaxial	0.1	Indented	35 mm	Continuous and stable bending and whipping
F3		0.2	Smaller	20 mm	Continuous and stable bending and whipping
F4		0.5	Double	13 mm	A combination of spraying and spinning

refers to sheath-to-core fluid flow rate ratio.
The values are estimated according to the size of spinneret shown in Figure 1(b).
