Principle of Electrospinning
Electrospinning technology: electrically charged polymer solution or melt is stretched and refined in high-voltage electrostatic field, accompanied by solvent volatilization or melt solidification, and becomes micro-nano-level fiber, which is deposited on the receiving device to form nano-fiber film material with a certain accumulation density.
Basic electrospinning device: High voltage power supply; Injection pump; Injection syringe; Spinning nozzle; Collection devices
Electrospinning driving force: electric field force
Conditions for the formation of spinning jets: electric field force > surface tension
