Electrospinning device

摘要

The present invention relates to an electrospinning device. The electrospinning device may apply the force of a supersonic flow acting at a predetermined angle with respect to an electrostatic force on a fiber discharged from an electrospinning nozzle to cause shearing stress on the fiber, thereby providing fibers having a very small diameter and collecting fibers having a finer diameter. Also, the electrospinning device may collect finer and more uniform fibers by adjusting the relative positions of the electrospinning nozzle for discharging the fiber and a gas spray nozzle for spraying a gas.

1. An electrospinning device comprising:
an electrospinning nozzle configured to discharge a polymer spinning solution by being applied with a high voltage in such a manner that the polymer spinning solution forms a fiber; a high voltage generator configured to apply a high voltage to the electrospinning nozzle; a ground power source configured to form an electric field in a space between the electrospinning nozzle and the ground power source so that the fiber discharged from the electrospinning nozzle is induced to flow in a predetermined direction by an electrostatic force; a gas spray nozzle configured to spray a gas in one direction; a collector configured to collect the fiber discharged from the electrospinning nozzle thereon, wherein the collector has a collection surface on which the fiber is collected, and the collection surface of the collector is disposed to face the gas spray nozzle along the flow direction of the gas sprayed from the gas spray nozzle, and the fiber discharged from the electrospinning nozzle is collected on the collection surface of the collector by the flow force of the gas sprayed from the gas spray nozzle, wherein the ground power source is connected to the gas spray nozzle so that the fiber discharged from the electrospinning nozzle is induced to flow toward the gas spray nozzle by the electrostatic force, wherein the gas spray nozzle is configured to spray the gas at supersonic flow speed to form a supersonic gas flow which moves toward the collector, and wherein the electrospinning nozzle is disposed to be spaced apart from the supersonic gas flow discharged from the gas spray nozzle.
