Problems solved by technology

[0004] However, conventional electrospinning uses a planar receiver plate, and the resulting nanofibers are tightly packed and highly compressed, with major pore sizes of only 1 to 2 μm and a material thickness of no more than 500 μm.
Although the compact two-dimensional nanofibers are conducive to cell dispersion, they limit the migration and penetration of cells into the interior of the material.

[0028] See attached figure 1 And figure 2 This embodiment provides an electrospinning material receiving device 10a, which includes: a receiving plate 100a, a driving device 200 for driving the receiving plate 100 to rotate, and a refrigerating device for cooling the receiving plate 110.

[0029] The receiving plate 100a rotates under the driving of the driving device 200, so that it can uniformly receive the fibers ejected from the nozzles in different directions at the same time, realize bi-component or multi-component electrostatic spinning, and avoid fiber distribution due to the same kind of charge repulsion. Evenly. At the same time, the receiving plate 100a is cooled by the refrigerating device, so that the surface of the receiving plate 100a is low temperature, which in turn causes the water vapor in the air to condense during the spinning process to form ice crystals, which are used as porogens and supporting materials to make the electrospun fiber vertical Direction st...

Abstract

The invention discloses an electrospinning material receiving device and a manufacturing device for electrospinning. The electrospinning material receiving device comprises a flat receiving plate, a driving device for driving the flat receiving plate to rotate and a refrigerating device for refrigerating the flat receiving plate, wherein the driving device comprises a transmission mechanism and amotor, the power output end of the transmission mechanism is connected with the flat receiving plate, and the refrigerating device is connected to the flat receiving plate. The refrigerating device can refrigerate the flat receiving plate, so that ice crystals formed by condensing steam in air constantly grow in the spinning process and serve as a pore-foaming agent and a supporting material, anda spongy three-dimensional electrospinning material provided with communicated pores. The flat receiving plate can simultaneously and uniformly receive fiber sprayed from spraying heads in different directions under rotation, double-component or multi-component electrospinning is achieved, and ununiform fiber distribution caused by repulsion of the same electric charges is avoided.

Description

Technical field [0001] The invention relates to the field of spinning manufacturing, in particular to an electrospinning material receiving device and electrospinning manufacturing equipment. Background technique [0002] In recent years, nanotechnology has become a research frontier and research hotspot in the scientific community. Electrospinning is an important method for preparing nanofibers. It was first proposed by Fomhals in 1934. Electrospinning is a spinning process that uses electrostatic force to process polymers. Its principle is to use a high-voltage power supply to charge a melt or polymer solution to overcome surface tension and continuously spray to prepare nanofibers. [0003] The processing range of electrospinning technology covers almost all natural materials and synthetic materials, even proteins, polysaccharides, nucleic acids and biologically active substances, which are widely used in materials science, biotechnology, tissue engineering, environmental prote...
