Coaxial Grooved Nozzle for Multi―Jet Electrospinning, System and Appratus for Multi―Jet Electrospinning using the Coaxial Grooved Nozzle, Method for Fabrication of Nanofibers with High―Throughputs using the Multi―Jet Electrospinning

摘要

PURPOSE: A coaxial grooved nozzle for multi-jet electrospinning is provided to supply electroconductive solvent and to enable multi-jet electrospinning by one nozzle. CONSTITUTION: A nozzle of multi-jet mode for electrospinning comprises: an internal nozzle(11) which is formed in a hollow pipe and disperses solvent to each grooves by voltage; and an external nozzle(12) which disperses solution to each groove according to the movement of the solvent and emits the solution to a nanofiber collection plate by multi-jet mode. The nozzle further comprises metal internal structure which enhances ion transfer area of the solvent and solution.
