Background

Electrospinning is a special form of electrostatic atomization of high molecular fluids, a special fiber manufacturing process in which a polymer solution or melt is jet spun in a strong electric field. Under the action of the electric field, the liquid drop at the needle head changes from a spherical shape to a conical shape, and a fiber filament is obtained by extending from the tip of the conical shape. In this case, the atomized material is not in the form of fine droplets, but rather of fine polymer jets, which, after a relatively long travel, finally solidify into fibers. The preparation of nanofibrous materials through electrostatic spinning technology is one of the most important academic and technical activities in the field of materials science and technology in the world in recent decades. Electrostatic spinning has become one of the main approaches for effectively preparing nanofiber materials due to the advantages of simple manufacturing device, low spinning cost, various spinnable substances, controllable process and the like.
