A porous bubble electrospinning device

Abstract

A multihole bubble electrostatic spinning device comprises a liquid storage tank, a high-voltage electrostatic generator, an air pump, a receiving portion arranged right above the liquid storage tank, a metal electrode and a grounding electrode connected with the receiving portion, wherein the liquid storage tank is opened at the upper end and connected with the high-voltage electrostatic generator through the metal electrode, a multi-coil rotary metal gas-guide tube is placed in the solution of the liquid storage tank and connected with the high-voltage electrostatic generator through the metal electrode, the air pump is connected with the rotary metal gas-guide tube, and a plurality of small holes penetrate through a round portion of the multi-coil rotary metal gas-guide tube. According to the device, the multi-coil rotary metal gas-guide tube provided with the plurality of the small holes is arranged, therefore the solution brought by the tube can generate a large amount of nanofibers under the action of electrostatic force when the multi-coil rotary metal gas-guide tube rotates, and efficient, and continuous production with low energy consumption for micron or nanofibers can be achieved.

AI Technical Summary

Problems solved by technology

[0005] The traditional nano-electrospinning technology has some defects, such as low output, and it is greatly affected by the solubility and viscosity of the solution, and because the needle diameter is small, it is easy to block the needle

In response to these problems, Professor He Jihuan proposed the bubble electrospinning method. However, this method is still in the laboratory preparation stage, and the uniformity of the bubble generation is difficult to control, and it cannot be mass-produced industrially. The production of nanofibers is still an urgent problem. needs to be resolved
