The invention discloses an electrostatic spinning device having a porous nozzle. The electrostatic spinning device includes a spinning receiving plate, a porous nozzle silk spraying device used for spraying nano fibers, a spinning solution storage device, a pressure pump used for transporting a spinning solution to the porous nozzle silk spraying device, and a high-voltage generator used for providing high-voltage static electricity for the porous nozzle silk spraying device; the porous nozzle silk spraying device includes a silk spraying container made of insulating materials, the top of the silk spraying container is provided with a plurality of silk spraying holes communicated with an inner cavity of the silk spraying container, each silk spraying hole is internally provided with a metal nozzle, and all the metal nozzles are communicated with each other and connected with the high-voltage generator; the two ends of the pressure pump is connected with an inner cavity of the spinning solution storage device and the inner cavity of the silk spraying container through the spinning solution conveying pipes respectively. The electrostatic spinning device can effectively solve the pollution problem of a spinning solution and the solvent evaporation problem of the spinning solution, the rejection phenomenon between sprayed jet flow does not occur, and a prepared nano fiber membrane is uniform in distribution.

Description

technical field [0001] The invention relates to an electrostatic spinning device, in particular to an electrostatic spinning device with a porous nozzle. Background technique [0002] Nanofibers have the characteristics of ultra-high specific surface area, extremely large aspect ratio, and superior mechanical properties. They have broad application prospects in various fields such as environmental engineering, tissue engineering, drug release, energy storage, and sensors. At present, the most direct method that can effectively prepare nanofibers is the electrospinning method. With the increasing demand for nanofibers in the market, the most widely used electrospinning methods that can prepare nanofibers in high batches in the laboratory or industry are multi-needle electrospinning devices and needle-free electrospinning. wire device. [0003] Among them, in the needle-free electrospinning technology, static electricity is used to promote the formation of many spinning Tayl...
