Description

technical field [0001] The invention relates to an electrospinning device, in particular to a nanofiber diameter-controlled assisted induction batch electrospinning device. Background technique [0002] Due to the excellent electrical, mechanical, optical properties and high specific surface area of ​​nanofibers, they are widely used in fields such as filtration, battery separators, and biological tissue engineering, and their market share in emerging fields such as electronics and energy is also increasing. rise, so it has a huge market prospect. [0003] Due to its own advantages, such as simple system, fast speed, low cost, continuous fiber, small and uniform diameter, etc., electrospinning technology has gradually become the main technology for preparing nanofibers. However, the traditional electrospinning technology usually uses a single needle as the spinneret, which is inefficient and the output is very low, so the electrospinning nanofiber batch device has become th...

Problems solved by technology

Such as blowing induced electrospinning (Y.Liu, J.H.He, et al, Biomimic fabrication of electrospun multiple nanofibers with high-throughput [J]. Chaos Solution and Fractals, 2008, 37, 643-651), using the induction effect of auxiliary airflow fibers Uniformity is improved, but this method has low yield, and the auxiliary gas flow control is difficult to ensure the stability of the process

Another example is that the Chinese patent CN200910235204 discloses a kind of electrospinning device for mass production of nanofibers, and the output is significantly improved, but verification experiments show that droplets are prone to appear, and the diameter of the prepared nanofibers is very uneven.
