Description
technical field [0001] The invention relates to an electrospinning device for preparing multi-scale nanofibers, belonging to the technical field of electrospinning. Background technique [0002] Compared with traditional electrospinning, multi-scale nanofibrous membranes have higher specific surface area, better mechanical properties, and better biocompatibility, so multi-scale nanofibrous membranes are used in environmental, biomedical and energy fields. etc. have good application prospects. The multi-scale nano-mesh structure can increase the specific surface area and porosity of the material, reduce the filtration resistance, and improve the filtration and adsorption of nanofiber membranes. In the prior art, multi-scale nanofiber membranes are usually prepared by adding additives to the spinning solution to make the generated jets unstable. Influence, reduce spinning efficiency, and even lead to spinning failure. SUMMARY OF THE INVENTION [0003] The purpose of the p...
