Abstract

The invention provides an electrostatic spinning production method and device to solve the technical problems that the transmitting voltage requirement is high and the production efficiency is low in current electrostatic spinning production. The production method includes the steps that 1, a liquid film layer is formed by a solution; 2, an electrostatic field is formed between a collecting plate and the solution; 3, a gas film layer is formed under the liquid film layer; 4, the liquid film layer forms a Taylor cone and then forms solution jet flow under the electrostatic field, the solution jet flow moves towards the collecting plate, and then nanofibers are generated on the collecting plate. The electrostatic spinning production device comprises the grounded collecting plate and further comprises a porous pipe arranged below the collecting plate, wherein the liquid film layer is formed on the surface of the porous pipe, and the porous pipe is connected with a high-voltage power supply and can rotate in the circumferential direction. The electrostatic spinning production method and device can reduce the electrostatic spinning transmitting voltage and improve the electrostatic spinning production efficiency 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...
