INJECTION NOZZLE FOR ELECTROSPINNING AND ELECTROSPINNING DEVICE USING THE SAME

摘要

The present invention relates to 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 nozzle body and the second nozzle body. The electrospinning device basically performs air electrospinning for injecting liquid fiber material together with air while discharging the liquid fiber material via the nozzle members, and pure electrospinning without air injection can be stably carried out by separating the second nozzle body in such a manner that the lower ends of the nozzle members are exposed by a predetermined length or more. Therefore, according to the present invention, pure electrospinning, air electrospinning or hot air electrospinning may be selectively carried out.
