ELECTROSPINNING APPARATUS COMPRISING TEMPERATURE ADJUSTMENT DEVICE, PREPARATION METHOD, FOR NANOFIBERS OR NANOMEMBRANE, USING SAME, AND NANOFIBERS OR NANOMEMBRANE PREPARED BY MEANS OF SAME

摘要

The present invention relates to an electrospinning apparatus comprising a temperature adjustment device, a preparation method, for nanofibers or a nanomembrane, using same, and nanofibers or a nanomembrane prepared by means of same and, more specifically, to a method in which nanofibers or a nanomembrane are prepared by electrospinning a spinning solution, which comprises a high concentration polymer, at a temperature that is higher than the room temperature which is the existing electrospinning temperature. In addition, the present invention relates to an electrospinning apparatus which has an overflow system reusing a spinning solution, which has not been nanofiberized, and comprises a temperature adjustment device for, instead of maintaining the concentration of a spinning solution being electrospinned, maintaining the viscosity of the spinning solution, thereby not having to use a diluting agent. Also, the present invention relates to a method in which: nozzle tube bodies, which have provided a plurality of pin-type nozzles, are arrayed in the MD direction or CD direction of a substrate that is provided inside a unit of an electrospinning apparatus; each nozzle tube body and nozzle are controlled; and adjusted is the spinning amount of a polymer spinning solution that is being electrospinned in the MD direction or CD direction of the substrate, thereby adjusting the base weight of a nanomembrane being laminated on the substrate.
