Description

technical field [0001] The invention belongs to the field of nanofiber material preparation, and in particular relates to a receiving device for electrostatic spinning. Background technique [0002] Electrospinning, also known as electrospinning, electrostatically atomizes the polymer fluid (the fluid can be a solution or a melt), splits it into tiny polymer jets, and solidifies to form fibers during the jet injection process. The electrospinning device mainly consists of four parts: spinneret, receiving device, polymer fluid supply system and high-voltage electrostatic generator. The specific working principle is: the polymer fluid supply system supplies the polymer fluid to the tip of the spinneret, and at the same time The high-voltage electrostatic generator (thousands to tens of thousands of volts output) acts on the tip of the spinneret, and a large amount of electrostatic charge is generated on the surface of the fluid droplet at the tip of the spinneret, so that the ...

Problems solved by technology

Within 48 hours after spinning, the fiber mat is immersed in a solvent, pre-frozen, and then freeze-dried to obtain a three-dimensional three-dimensional scaffold with large pores and holes interpenetrating with each other. The original structure of nanofibers will be destroyed during processing

[0007] In summary, there are still great challenges and limitations in obtaining three-dimensional nanofiber assemblies, and at the same time, the specific electrospinning techniques that are currently disclosed can only achieve a single specific type of nanofibers, so it is necessary to improve
