(a) Multinozzle electrospinning system. Initial stability for (b) normal electrospinning and (c) electrospinning with auxiliary electrodes.
Velocity gradient profiles for (a) a normal nozzle tip and (b) a nozzle tip with an auxiliary electrode. The inset graph shows the deformation behavior of the initial spun solution.
Size distribution and SEM micrographs of electrospun fibers (a) for a normally electrospun nanofiber web and (b) for a nanofiber web electrospun with an auxiliary electrode.
WAXD graph of the PCL nanofiber webs obtained from electrospinning with and without an auxiliary electrode: (a) the scanning results of nanofibers collected at a collector take-up speed of and [(b) and (c)] the azimuthal scans of the (110) reflection for various collector velocities.
