Design and Implementation of an Electrospinning System

In today's world, reducing the size of materials to a submicron scale brings numerous possibilities in various areas, such as the production of electrically conductive nanofibers, high-performance filters, biomaterial polymers, and tissue scaffolds. Electrospinning is one of the most promising methods for depositing nanoscaled fibers from a variety of polymer solutions. However, the typical obstacle of electrospun fiber production is the bending instability due to the complicated oscillations of a polymer jet. This uncontrolled fiber formation hinders the implementation of electrospinning in the industry.The aims of this chapter are to provide a brief introduction to the electrospinning process for obtaining nanofibers, including the up-to-date novel modeling techniques. Moreover, the feasibility of suppressing the bending instability due to the complicated oscillations of a polymer jet is investigated, along with experimental observations and developed mathematical models. It was shown that the auxiliary electric fields applied through the jet trajectory notably increased the controlled deposition of the polymer fibers at the collector.
