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

Figure 2

Observations of the electrospinning processes: (a) a digital picture showing the arrangement of apparatuses of the modified coaxial electrospinning system, the bottom-right inset showing the connection of the spinneret with power supply using an alligator clip; (b) a digital picture showing the clogging phenomenon during the single-fluid electrospinning of core EL100 solution; ((c)–(f)) digital pictures showing the production of F3 to F6 using the modified coaxial electrospinning under a shell-to-core fluid flow rate ratio of 0.1 to 0.2, to 0.3, and to 0.5, respectively. The applied voltage was fixed at 14 kV. The left-bottom insets show an enlarged view of the Taylor cone corresponding to the modified coaxial processes.
