Abstract
Today, nanosized structures have a remarkable impact on technological advancements in biomedical, bioengineering, and environmental applications. Electrospinning is an efficient and versatile technique for the fabrication of nanostructures made of fibers with a high surface-to-volume ratio. This technology produces nanofibers starting mostly from solutions of a wide variety of polymers via a proper polymer-solvent selection. The extreme elongation and narrowing of the fiber occur because of electrostatic repulsive forces on the charged jet. By fine-tuning the processing variables, it is possible to control the fiber diameter and consequently the mat porosity. Furthermore, depending on the nozzle structure and collecting mode, it is possible to realize fibers with various morphologies, thus adding an extra level of complexity to the nanostructured mat.
