Wang, Xin and Niu, Haitao and Lin, Tong and Wang, Xungai (2009) Needleless electrospinning of nanofibers with a conical wire coil. Polymer Engineering and Science, 49 (8). pp. 1582-1586. ISSN 0032-3888

Abstract

In this article, we have demonstrated a novel needleless electrospinning of PVA nanofibers by using a conical metal wire-coil as spinneret. Multiple polymer jets were observed to generate on the coil surface. Up to 70kV electric voltage can be applied to this needleless electrospinning nozzle without causing 'corona discharge.' Compared with conventional needle electrospinning, this needleless electrospinning system produced finer nanofibers on a much larger scale, and the fiber processing ability showed a much greater dependence on the applied voltage. Finite element calculation indicates that the electric field intensity profiles for the two systems are also quite different. This novel concept of using wire coil as the electrospinning nozzle will contribute to the further development of new large-scale needleless electrospinning system for nanofiber production.
