Abstract
(EN)
The present invention relates to an electrospinning device for the uniform spinning of polymer nanomaterials using moving charges, the electrospinning device being characterized by comprising: a spinning nozzle through which a spinning solution made of polymer nanomaterials is discharged; a collector in which the spinning solution, made of polymer nanomaterials and discharged from the spinning nozzle, is collected as nanofibers; and a power supply unit for applying power to the spinning nozzle and the collector. The collector includes a base layer in which the nanofibers are collected in a web state, and a plurality of conductive dots arranged in a plurality of rows and a plurality of columns on the bottom surface of the base layer. The electrospinning device is also provided with a relay for selectively applying the power, applied from the power supply unit, to the plurality of conductive dots.
