摘要

The present invention relates to an electrospinning composite nozzle, an electrospinning apparatus including the same, a method for producing a nanofiber structure, and a method for producing a nanofiber structure, a polymer nanorod and a polymer nanorod, and a drug carrier using the polymer nanorod will be. The electrospinning composite nozzle of the present invention comprises an outer nozzle and two or more inner nozzles arranged side by side inside the outer nozzle, and using the electrospinning apparatus of the present invention comprising the electrospinning composite nozzle When preparing a nanofiber structure, a novel nanofiber structure comprising a core nanofiber in which at least two components are formed in a discontinuous and intersected or uncrossed state and a sheath nanofiber surrounding the core nanofiber. Can be prepared. In addition, by selectively removing only the sheath nanofibers from the nanofiber structure of the present invention, a polymer nanorod can be easily obtained. In particular, when manufacturing the nanofiber structure of the present invention, when using a hydrophilic polymer material and a hydrophobic polymer material as a component of the core nanofibers can be prepared amphiphilic polymer nanorods. In addition, when manufacturing the nanofiber structure of the present invention, by controlling the applied voltage, the electrical conductivity of the spinning solution and the dissolution rate, it is possible to easily control the length and diameter of the polymer nanorods.
