US 2010/0148405 A1 · NANOFIBER PRODUCING METHOD AND NANOFIBER PRODUCING APPARATUS

Abstract

An object of the present invention is to stabilize the properties of nanofibers produced. Solution prepared by dissolving a polymeric substance in a solvent is supplied into a conductive ejection container having a plurality of ejection holes. The ejection container is rotated and electrostatic explosions of the solution discharged through the ejection holes are caused so that nanofibers are produced. In the above method for producing nanofibers, in the case where the amount of the solution contained in the ejection container exceeds a predetermined amount, the amount of the solution exceeding the predetermined amount overflow the ejection container. The overflowed solution is collected and resupplied to the ejection container.
