Abstract
An injection nozzle for electrospinning including a first nozzle body and a second nozzle body detachably coupled with each other and nozzle members inserted in the first and second nozzle bodies and an electrospinning device using the nozzle. The electrospinning device basically performs air electrospinning wherein a source liquid for fiber is injected together with air while the source liquid for fiber is discharged through the nozzle members, and pure electrospinning without air injection can be efficiently carried out by separating the second nozzle body in such a manner that the lower ends of the nozzle members are exposed for a predetermined length or more. Therefore, according to the present invention, pure electrospinning, air electrospinning or hot air electrospinning may be selectively carried out.
