Improvement of Uniformity of Needleless Electrospun Nanofibers

Abstract:

Polyvinyl alcohol (PVA) water solution was electrospun using both needle electrospinning and needleless electrospinning methods. Finer and uniform nanofibers were obtained from disc and coil electrospinng, when compared to those of conventional needle electrospinning. The finest nanofibers were 217±86 nm and 234±82 nm in diameter from disc and coil electrospinning respectively, while fibers from needle electrospinning was 296±36 nm when the applied voltage was 12kV. However, needle electrospinning produced nanofibers with a more uniform diameter distribution.
