METHOD AND DEVICE FOR PRODUCTION OF NANOFIBERS BY ELECTROSTATIC SPINNING OF POLYMER SOLUTION OR MELT

摘要

Method and device for production of nanofibers by electrostatic spinning of polymer solution or melt The invention relates to a method for production of nanofibers by electrostatic spinning of a polymer solution or a polymer melt in an electric field of high intensity created by a potential difference between a spinning electrode (31) and a counter electrode (32), which are composed of mutually parallel oblong bodies, whereby spinning is performed from the surface of the polymer solution or the polymer melt on the spinning electrode (31) and the created nanofibers (5) are by to the action of the electric field carried towards the counter electrode (32). Spinning is carried out from the surface of the polymer solution or polymer melt on the spinning electrode (31) against at least one pair of counter electrodes (32), which are in relation to the spinning electrode (31) arranged in the same distance and the angle between the planes interlaid by the spinning electrode (31) and both counter electrodes (32) of the corresponding pair of counter electrodes (32) is in the range of 40° to 180°, whereby streams of nanofibers (5) which are directed to each of the counter electrode (32) are before falling on the corresponding counter electrode (32) deflected by the action of the additional force acting in a direction across the stream of nanofibers (5) and are carried by this additional force towards a collecting place (4) of nanofibers (5). The invention also relates to a device for production of nanofibers.
