Electrospinning technique and its application

Metal oxide nanomaterials are widely used in many applications of renewable energy. Ytterbium oxide (Yb2 O3 ) also attracts attention due to its similar structure to ZnO (~3,26 eV) and TiO2 (~3,36 eV) in terms of bandgap energy. In this study, Yb2 O3 belonging to the lanthanide oxide family was produced as nanofiber forms by using the electrospinning technique, which allows for large-scale production, for the first time.

Electrospinning is an electro-hydrodynamic process, when a polymer solution can be spun by the use of high potential electric field to obtain nanofibers. Electrospinning techniques are a gainful and flexible method to apply electrostatic force to form fibers in the 100nm range. Electrospinning instrument have mainly three components in which a supply of high voltage, a spinneret and target collector plate. Electrospun fibers have a lot of structural and functional advantages.

The electrospinning process is highlighted with the ability of fabricating fibers with diameters on the nanometer scale, small inter-fibrous pore size and high porosity, vast possibilities for functionalization with high surface area to volume or mass ratio, ease of use and instrument setup, and adaptability. It attracted a great deal of attention due to its unique properties. Different polymers have been successfully electrospun into ultrafine fibers using this technique including synthetic polymers such as polyurethane (PU).
