Formation of oriented nanofibers using electrospinning

Abstract

This letter reports on a simple, easy method for generating suspended nanofibers on a dielectric substrate using various target electrodes. By controlling the electrostatic field between the target electrodes, the nanofibers can be oriented to the electric field direction at the electrodes. The alignment of nanofibers was dependent on the applied frequency, field strength, and shape of the electrode.

Polycarprolactone ultrafine fiber membrane fabricated using a charge-reduced electrohydrodynamic process

“…The detailed function and computer-simulated results of the auxiliary electrode are described elsewhere. 8,9 The guiding electrodes are very important in electrospinning material for wound dressings to ensure that the electrospun fibers are deposited stably on the desired target plate. Figure 2 shows high-speed photographs of electrospun ultrafine fibers going past the guiding electrodes.…”

Strong Orientation of Polymer Chains and Small Photochromic Molecules in Polyamide 6 Electrospun Fibers

“…[1,[18][19][20] Two conductive strips separated by a gap of few centimeters were used as collector, thus forcing the fibers to align themselves perpendicular to each edge of the gap (Figure 1 b). The resulting fibers turned out to be strongly aligned.…”

Well‐aligned Nano‐fiberous Membranes Based on Three‐pole Electrospinning with Channel Electrode

“…[12][13][14] Subsequently, the use of an array of parallel strip electrodes was developed to increase the size of the electrospun membrane. [15] Regarding this parallel electrode approach, it is reported that the dielectric property of the electrodes can strongly affect the degree of alignment. [16] According to theoretical and experimental studies, the gap size is also a critical parameter that influences the membrane morphology.…”
