Problems solved by technology
[0004] 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
[0005] The proposal of the air bubble electrospinning method has improved the above-mentioned problems very well. However, this method is still in the stage of laboratory preparation, and the uniformity of air bubble generation is difficult to control, and it cannot be mass-produced industrially. The production of nanofibers is still a problem. Urgent need to solve
