Nanofibers are ultrafine fibers with diameters in the nanometer range, significantly smaller than conventional textiles. Beyond standard thermoplastic polymers, production encompasses ceramic nanofibers such as alumina, zirconium oxide, and titanium oxide. These materials are essential in applications ranging from high-performance filters and protective masks to regenerative medicine.
Electrospinning is a primary method for producing these nanofibers. Capable of spinning various materials with diameters typically between 50 and 500 nm, the process is widely adopted for its simplicity and effectiveness.
In the electrospinning process, a polymer solution or melt is dispensed from a syringe or capillary while a high voltage is applied. When the voltage exceeds a critical threshold, electrostatic repulsive forces overcome the surface tension at the liquid tip. This ejects a continuous charged jet that elongates and dries as it travels toward a collector, forming accumulating layers of ultrafine fibers.
Standard electrospinning setups typically utilize positive DC high-voltage power supplies ranging from 10 kV to 30 kV. However, specific applications--depending on the polymer solution, target fiber diameter, and deposition rate--may require voltages exceeding 50 kV, negative polarity outputs, or high-speed high-voltage amplifiers.
