Electrostatic spinning is a low-cost, environmentally friendly and efficient spinning method. It mainly sprays polymer solution by installing electrostatic field and airflow to form fibers. Electrostatic spinning can be used to produce many functional materials. In the process of electrospinning, due to the interaction between fiber and electrostatic field, the rated size of fiber is very small, usually in nanometer scale.

The practical application of electrospinning is very extensive, especially in the fields of medicine and health care. Electrospinning technology can produce a very soft material with super-filamentous nano-capillary structure, which can be used to make many practical materials for cell culture and tissue engineering. In addition, electrospinning products are also used in manufacturing applications, such as micro-filtration elements, protective masks, dust masks and isolation masks.

Compared with other fibers manufactured by traditional production methods, electrospun fibers have many excellent characteristics. Electrospun fibers can have higher specific surface area and higher storage capacity, thus having better strain capacity. In addition, the fiber prepared by electrospinning has a large surface area and can form good adsorption, so it has better performance than nanoparticles in filtration, biological probe and so on, and has a very wide application value.
