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. |
