Description

TECHNICAL FIELD

[0001] The utility model belongs to electrospinning technical field, especially relate to an electrode electrospinning device. BACKGROUND

[0002] Needleless electrospinning is a new type of electrospinning technology, which has the advantages of high fiber yield, simple equipment structure, easy use and maintenance. Compared with conventional needle electrospinning technology, needleless electrospinning can greatly improve the yield of nanofibers. Needleless electrospinning utilizes electric field force to overcome surface tension to eject polymer solution from the spinneret to form ultrafine fluid jet. Under the combined action of electrostatic field force, surface tension, viscous force and charge repulsion force, the solution jet is gradually drawn and thinned, accompanied by solvent evaporation, and finally micro-nano fibers are deposited on the collecting electrode.

[0003] Needleless electrospinning technology has become a research hotspot in the field of nanofiber preparation. For example, document 1 (Chinese patent CN201020650021.5, spiral blade nanofiber generator and electrostatic spiral spinning device) and document 2 (Chinese patent CN201610569146.7, a needleless electrospinning assembly based on fractal structure) use spinning head rotation or melt flow attachment on a circular surface to form a free surface of solution or melt, and electrospinning is carried out under the action of electrostatic field. However, the electrode plates in these patents have electric field interference between them, which affects the uniformity of nanofibers in the transverse direction, and there is also the problem of fast solvent evaporation speed. Document 3 (Chinese patent CN200880025156.8, spinning method of liquid matrix, device for producing nanofibers by electrospinning of liquid matrix, and spinning electrode for the device) uses a static metal wire as a spinning electrode to perform electrospinning by reciprocating liquid coating. This method uses a reciprocating liquid coating device that changes the electric field of the spinning electrode, affecting the spinning process and nanofiber quality, and also has the problem of low nanofiber yield.
