The term "electrospinning" comes from "electrospinning" or earlier "electrostatic spinning", which is generally referred to as "electrospinning" and "electrospinning" in China.
The word "electrospinning" comes from "electrospinning" or earlier "electrostatic spinning", which is generally referred to as "electrospinning" and "electrospinning" in China. In 1934, the Formalas invented the experimental device for preparing polymer fibers with electrostatic force, and announced how the polymer solution forms a jet between the electrodes. This is a detailed description of the device for preparing fibers using high-voltage static electricity, which is recognized as the beginning of the preparation of fibers by electrostatic spinning technology. However, from the perspective of scientific basis, this invention can be regarded as a special case of electrostatic atomization or electrospray, and its concept can be traced back to 1745. The difference between electrostatic atomization and electrostatic spinning is that the working media used are different. The electrostatic atomization uses a low-viscosity Newtonian fluid, while the electrostatic spinning uses a higher-viscosity non-Newtonian fluid. In this way, the study of electrostatic atomization technology also provides a theoretical basis and foundation for the electrostatic spinning system. In-depth study of the electrospinning process involves electrostatics, electrohydrodynamics, rheology, aerodynamics and other fields.
During the 1930 s and 1980 s, the development of electrostatic spinning technology was relatively slow, and most of the researchers focused on the research of electrostatic spinning devices, and released a series of, but not yet attracted attention. In the 1990 s, the Reneker research team of Akron University carried out in-depth research on the process and application of electrospinning. Especially in recent years, with the development of nanotechnology, electrospinning technology has been developed rapidly, and scientific research and industrial circles around the world have shown interest in this technology. During this period, the development of electrospinning technology has roughly gone through four stages: the stage mainly studies the spinnability of different polymers and the influence of process parameters on fiber diameter and properties during the spinning process, as well as the optimization of process parameters; the stage mainly studies the diversification of the composition of electrospun nanofibers and the fine control of their structure; the third stage mainly studies the application of electrospun fibers in energy, environment, biomedicine, optoelectronics and other fields; the fourth stage mainly studies the mass manufacturing of electrospun fibers. The above four stages are intertwined and there is no clear boundary.
