Embodiment 1

[0045]The structure of the polymer solution electrospinning assembly in Example 1 of the present invention will be described in detail with reference to FIG. 1 (1). As shown in Figure 1 (1), the polymer solution electrospinning assembly includes a first electrode 01, a second electrode 03 placed opposite to the first electrode 01, and a second electrode 03 located between the first electrode 01 and the second electrode. Spray mechanism 02 between electrodes 03. Wherein, the spraying mechanism 02 is used to spray the polymer solution on the surface of the first electrode 01. In order to have a larger spinning area for polymer solution electrospinning, this embodiment limits the first electrode 01 to be a flat plate electrode. The shape of the second electrode 03 is not limited, and it may be a cylindrical electrode, a flat plate electrode, or an electrode of other shapes. As long as an electrostatic field can be formed between the first electrode 01 and the second electrode 03...

Abstract

The invention provides a polymer solution electrostatic spinning component, a device and a method. The spinning component comprises a first electrode, a second electrode which is placed opposite to the first electrode, and a spraying mechanism which is positioned between the first electrode and the second electrode, wherein the first electrode is a plate electrode; and the spraying mechanism is used for spraying solution to the surface of the first electrode and is provided with a flat plate and a scraping cutter. Because the first electrode with a large area is used, a large-area spinning region can be formed, and the spinning efficiency is greatly improved. The flat plate in the spraying mechanism is used for flatly spraying a newly-sprayed spinning solution, and the scraping cutter can be used for removing the residual old solution of the previous spinning to prevent a new solution from being mixed with the old solution, so that the spinning quality is improved.

Description

technical field [0001] The invention relates to the preparation technology of polymer nanomaterials, in particular to a polymer solution electrospinning component, device and method. Background technique [0002] Electrospinning technology is an effective method to prepare polymer nanomaterials, and one-dimensional fibers with diameters ranging from tens to hundreds of nanometers can be obtained. Compared with conventional fibers, nanofibers have higher porosity and specific surface area. This has led to extensive research and application of electrospinning technology in the field of filtration. [0003] Common single-needle electrospinning equipment is mainly composed of high-voltage source, spinning pump, spinning needle and collecting plate and other components. Through a high-voltage power supply, a high-voltage electrostatic field is formed between the spinning needle and the collecting plate. Under the action of the electrostatic field, the polymer solution droplet a...
