The authors developed a very simple alignment technique by which highly aligned polymer nanofibers of length > 25 cm were electrospun over a lateral range as large as 63 cm. This technique is based on a modified configuration, application of a tip collector, and sideward ejection. The salient feature of the electrospinning process is the production of single nanofibers one by one, which was clearly confirmed by real-time images taken by a high-speed camera. Aligned polycaprolactone, polyacrylonitrile, and carbon nanofibers were prepared by this method. (c) 2007 American Institute of Physics.
