A rotating film bubble electrospinning device

Abstract

A rotary film babble electrostatic spinning device comprises a film babble generator, a high voltage electrostatic generator, a draught fan, a receiver, a motor, a liquid storage tank, a positive metal electrode and a negative metal electrode. The film babble generator is arranged between the draught fan and the receiver, the draught fan is arranged behind the film babble generator, the receiver is arranged right in front of the film babble generator, the receiver is used for receiving the jet flow jet by the film babble generator, the film babble generator is connected with the high voltage electrostatic generator and the motor, the motor drives the film babble generator to make rotational motion, the liquid storage tank is arranged below the film babble generator and is used for supplying liquid to the film babble generator, the positive metal electrode and the negative metal electrode are electrically connected with the film babble generator and the receiver respectively, and voltage difference is formed between the positive metal electrode and the negative metal electrode. By means of the rotary film babble electrostatic spinning device, continuous spinning is achieved.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to a rotating thin film bubble electrostatic spinning device. Background technique [0002] Electrospinning technology is currently one of the most direct and basic methods for preparing ultrafine fibers and nanofibers, because the nanofibers prepared by electrospinning technology have ultra-high specific surface area, extremely large aspect ratio, and high surface activity. , Superior mechanical properties (high strength and high toughness), etc., have very broad application prospects in different fields such as textile engineering, environmental engineering, biotechnology, medical and health care, energy storage, military and anti-terrorism security. [0003] At present, the preparation of nanofibers in laboratories and industries widely adopts single-nozzle or multi-nozzle syringe electrospinning nanofiber devices. Such as Chinese patents ZL200410025622.6, ZL200420107832.5, etc...

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, the inventors of the patent application of the present invention proposed a bubble electrospinning method, but this method is still in the laboratory preparation stage, and the uniformity of bubble generation is difficult to control, and cannot be mass-produced industrially. Yield issues remain urgent
