Circular revolving brush electrostatic spinning device and use method of same

Abstract

The invention relates to a circular revolving brush electrostatic spinning device comprising a liquid supplying system, a brush type spinning system and a nano-fiber collecting system. The brush type spinning system comprises a brush head, a brush shaft, a cylindrical seat and a metal annular sprayer; the brush head is installed on the tail end of the brush head; the cylindrical seat is mounted on the brush shaft; the metal annular sprayer is arranged in a place on the upper end of the cylindrical seat and corresponding to the brush head; a bearing is arranged on the lower end of the cylindrical seat and on the brush shaft; the bearing is connected with a motor via a belt; the liquid supplying system has an air bottle, a spinning liquid storage bottle and a liquid guiding pipeline; the liquid guiding pipeline is disposed in the brush shaft; the upper end of the liquid guiding pipeline is connected with the brush head and the lower end extends into the bottom of the spinning liquid storage bottle; and the spinning storage bottle is connected with the air bottle via an air pipe. High-polymer solution can be automatically fed and nano-fibers can be prepared in batches in a stable way; and meanwhile, problems of volatilization of solvent during the electrostatic spinning and uncontrollability of the nano-fiber structure can be solved.

Description

technical field [0001] The invention belongs to the technical field of nano electrospinning and textile machinery, and in particular relates to an annular rotating brush type electrospinning device and a use method thereof. Background technique [0002] When polymer fiber diameters are reduced from the micrometer scale to the submicrometer or nanometer scale, a surprising set of properties emerges. Such as a very large volume specific surface area, the volume specific surface area of ​​nanofibers is basically 1000 times that of microfibers; it can be flexibly functionalized on the surface; it shows superior effects and mechanical properties compared with other known material forms, such as surface And interface effect, small size effect, quantum size effect and quantum tunneling effect and stiffness, tensile strength, etc. These outstanding properties make nanofibers the material of choice for many important applications, and have great development potential in the fields o...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a ring-shaped rotating brush-type electrospinning device and its use method, which solves the problem that the spinning direction is limited in the current electrospinning process, the solvent is easy to volatilize, the solution is not fully utilized, and the general free liquid In the face of long-term fluctuations in the concentration of spinning solution, low yield of nanofibers, and non-oriented structure of the final nanofiber product, the spinning solution can be supplied and spun immediately, and the diameter of the final nanofiber has a narrow distribution, realizing the full three-dimensional space. Azimuthally placed spinning provides new possibilities for nanofiber material processing and structure control
