Description

technical field

[0001] The invention belongs to the related technical field of electrofluid nozzles, and in particular relates to an electrofluid nozzle device for electrospinning of melts. Background technique

[0002] With the development of nanotechnology, electrospinning, as the most promising process for preparing continuous nanofibers, has received widespread attention from both academic and industrial circles. The basic principle of electrospinning is based on electrohydrodynamic jet printing, that is, the polymer solution or melt overcomes the surface tension under a high-voltage electrostatic field of several thousand to tens of thousands of volts to generate a charged jet, which solidifies during the jet printing process and finally falls Fibers are formed on a receiving substrate. The fibers prepared by electrospinning have high specific surface area, high porosity and some special physical and chemical properties, and have broad application prospects in the fiel...
