Abstract

The present invention provides a production method and device of electrospinning to solve the technical problems of high emission voltage requirements and low production efficiency in the current production of electrospinning; the production method comprises a. forming a liquid film layer from a solution; b. An electrostatic field is formed between the collecting plate and the solution; c. A gas film layer is formed under the liquid film layer; d. The liquid film layer forms a Taylor cone under the electrostatic field and then forms a solution jet, and the solution jet flows to the collecting plate Direction movement, and then form nanofibers on the collection plate; and the production device of electrospinning, it includes the collection plate of grounding; It also includes the porous tube that is arranged under the collection plate and is used for forming liquid film layer on its surface, described The porous tube is connected with a high-voltage power supply, and the porous tube can rotate circumferentially; the invention can reduce the emission voltage of electrospinning and improve the production efficiency of electrospinning in application.

Description

technical field

[0001] The invention relates to the technical field of electrospinning, in particular to an electrospinning production method and device. Background technique

[0002] In the prior art, the production process of electrospinning is as follows, see figure 2 After dissolving the polymer with a solvent, the solution 11 flows out from the needle through the syringe 10 . Then the needle tube is connected to the positive pole of the high-voltage power supply, and the negative pole of the power supply is connected to the collecting plate 16. At this time, an electrostatic field is formed between the needle head and the collecting plate 16. After this, after the solution 11 is polarized by the electric field, a Taylor cone 12 is formed at the needle head. After the electric field force is greater than the surface force of the solution, the solution 11 is sprayed from the Taylor cone 12 to the collecting plate 16, and the solution is further stretched and thinned by t...
