Description

technical field [0001] The invention relates to a magnetic levitation centrifugal electrostatic spinning device, which belongs to the field of centrifugal electrostatic spinning. Background technique [0002] With the rapid development of nanotechnology, the research field of nanomaterials has been widely concerned, and the demand for nanofibers is also increasing. At present, there are many methods for preparing nanofibers, mainly including electrospinning, centrifugal spinning, stretching and two-component composite spinning. Electrospinning is a process in which a charged polymer solution or polarized melt forms a Taylor cone in an electrostatic field, forms a jet flow on the Taylor cone, and then refines it by solvent evaporation or melt cooling and solidification to obtain a fibrous substance. Process; Centrifugal spinning method is a method in which polymer melt is thrown out from pores to form fibers by means of centrifugal force and shear force generated by a high-s...

AI Technical Summary

Problems solved by technology

The fibers prepared by the melt electrospinning method are relatively thick, and the research progress and industrialization development are slow; the centrifugal spinning method requires a high-speed motor to maintain the high-speed rotation of the disc in order to achieve continuous spinning conditions, and the entire process consumes more electricity. The structure of the device is complicated, the operation is cumbersome, the safety performance is low, and the diameter of the prepared fiber is relatively thick

[0003] Regardless of the electrospinning method or the centrifugal spinning method, researchers have never stopped the research and development and improvement of technology, but most of them simply improve the centrifugal spinning process or the electrospinning nozzle, which has never been able to solve the problem

Chinese patent (patent number: ZL201410108867.9) drives the liquid storage device to rotate through the driving device, and the liquid is centrifugally spun under the centrifugal force. Although the output of the device is high, the structure is complex, the power loss is large, and the cost is relatively high.
