Title:
ELECTROSPINNING NOZZLE PROVIDED WITH GAS EJECTION MEANS
Document Type and Number:
WIPO Patent Application WO/2024/085475
Kind Code:
A2
Abstract:
The present invention relates to an electrospinning nozzle including: a hollow needle through which a spinning solution is discharged; and a gas ejection means having multiple air holes formed at circumferential areas radially spaced a predetermined distance apart therefrom, and discharging air through the air holes to generate an airflow flowing straight with respect to a charged filament jet by the spinning solution, thereby preventing the airflow from coming into direct contact with the spinning solution to stably form the filament jet at a spinning nozzle tip and thus adjusting the filament jet so as not to exceed a specific range.
