Abstract

The invention discloses an electrostatic spinning device for manufacturing nano fibers in an electromagnetic field with a coupling method. The electrostatic spinning device comprises a material basket, a piston, a spinning nozzle, a high-voltage power supply device, a receiving plate and a grounding power line. The electrostatic spinning device further comprises an electric conduction coil arranged between the spinning nozzle and the receiving board and right opposite to the spinning nozzle and the receiving board. Two electromagnets are arranged on the receiving board in parallel. The orientation of nano fibers collected by electrified polymer solutions is greatly improved under the action of the electromagnetic field which is large enough. Meanwhile, the positively charged coil is added in the flow jetting process of polymers, jet flow can be stabilized, the range of a Taylor cone is reduced, and the degree of order of the nano fibers is further improved. The electrostatic spinning device for manufacturing the nano fibers in the electromagnetic field with the coupling method is simple in structure, convenient to operate, easy to control and short in technological process.

Description

technical field [0001] The invention relates to an electrospinning device, in particular to an electrospinning device for preparing oriented nanofibers by an electromagnetic field coupling method. Background technique [0002] Electrospinning technology is a method of spinning nanofibers with simple operation, wide application range and relatively high production efficiency. The traditional electrospinning method is to use the electric field force to draw the polymer solution or melt from the capillary mouth to form a jet, and through the process of swinging, evaporating, and thinning, nano-scale disordered fibers are finally obtained. Nanofibers prepared by electrospinning technology have been widely used in optoelectronic devices, sensor technology, catalysis, filtration, and medicine. [0003] In many cases, controlling the orderly arrangement of fibers is very important for the desired function of the fibers, especially in the release and growth of proteins, and the jet...
