Technology
Electrospinning
Electrospinning consists on the deposition of fibers on a substrate through the application of a high voltage between a polymer solution and the sample. The polymer solution, usually disposed inside a syringe with a specific needle gauge, forms a jet driven by the electrostatic potential and is deposited on the substrate, that is connected to 0 potential (ground). The thickness of the resulting fibers can vary from the micrometer to a few nanometers. The thickness depends on some variables that must be precisely controlled in order to obtain a satisfactory coating.
The most important factors of the electrospinning process are the nature and viscosity of the solution, the applied voltage, the collector distance, the flow rate, the syringe gauge and the time of deposition. Rotatory collectors are also used to obtain coherent fiber directions.
