Description

technical field [0001] The invention discloses a spinning method, more specifically, the invention discloses an electrostatic spinning method and its industrial application. Background technique [0002] In recent years, with the rapid development of nanotechnology, the preparation of nanotechnology is constantly emerging. At present, the main methods for preparing nanofibers include drawing, template synthesis, phase separation, self-assembly, emulsion polymerization and electrospinning (Loscertales IG , BarreroA, Guerrero I, et al.

Problems solved by technology

[0003] The current method for preparing nanofibers is monopolar spinning, that is, electrospinning is used alone for positive or negative electrodes. The disadvantage is that only one solution can be prepared, and the combination of multiple solutions with different properties cannot meet the requirements, and the spinning speed is slow. , real industrialization brings defects, fiber diameter control can only be the same size, it is not possible to prepare fibers with different diameters in the same material
