Problems solved by technology
[0003] Traditional equipment cannot meet the needs of stable production of practical nanofibers. The reason is that the environment during spinning cannot be controlled and adjusted. In addition, since more than 75% of the spinning solution is a solvent, organic solvents will cause harmful substances to be discharged and pollute the environment.

Description
technical field [0001] The invention relates to the field of nanofiber preparation, in particular to an electrospinning device for preparing nanofibers through electrospinning technology. Background technique [0002] Electrospinning technology is the use of electrostatic force to prepare ultrafine fibers or yarns, usually in nanometer to micrometer size, from a solvent. The droplet is charged under the action of the electric field, and the electrostatic force will neutralize the surface tension to deform the droplet. When the electrostatic force is greater than the surface tension to a certain extent, the droplet will form a jet stream, which splits during the spraying process and dissolves the solvent. Evaporated to finally obtain nanofibers. Taylor cones are formed where the thin stream is ejected. If the intermolecular forces of the droplet are strong enough, the rivulet does not break apart and instead forms a bundle of charged rivulets. [0003] Traditional equipmen...
