Abstract
The invention relates to a spinning electrode (1) for producing polymeric nanofibers by electrospinning of a polymer solution or polymer melt, containing an inlet pipe (2) of the polymer solution or melt, which ends on its top face (3), whereby around at least a part of the mouth (20) on the top face of the inlet pipe (2) of the polymer solution or melt is formed a spinning surface (4) rounded downwards below the mouth (20), whereby the spinning surface (4) continues as a collecting surface (6) on the outer surface of the inlet pipe (2) of the polymer solution or melt.The invention also relates to a device for producing nanofibers by electrospinning of a polymer solution or melt, which is equipped with at least one spinning electrode (1) according to the invention.In addition, the invention relates to a method for producing nanofibers by electrospinning of a polymer solution or melt, which is based on using the spinning electrode according to the invention.
