Nanofibers can be obtained using electrospinning. By applying a high voltage to a polymer solution with a low, defined flow rate, a microjet is generated, which arises from the collapse of the Taylor cone. The applied high voltage accelerates the jet to the collector (Al foil) and the excess solvent evaporates on the way. Ceramic nanofibers can be obtained by calcining the polymer fibers by dissolving the metal salts previously in the spinning solution. By calcining the fiber mat in an inert atmosphere, conductive carbon wires are formed, which can be used for energy storage materials. In addition, nanofibers can be used for medical applications, for example, to improve wound healing. In this case, accelerated cell growth is observed along the fibers.
