Both polymer melts and polymer solutions can be spun for electrospinning. For the necessary draft to the fiber, the melt or solution is exposed to an electric field in the air gap and accelerated and stretched by this field. The deposition takes place, for example, on a further nonwoven which is attached in front of the oppositely conductive electrode.


In the case of solutions, the solvent, which is usually volatile, is evaporated in the air gap. The result is a nonwoven coated with fibers of very thin diameters. Depending on the conditions (e.g. polymer, solvent, concentration, additives), fibers from the lower micrometer to the nanometer range can also be obtained.


Technical Equipment:

  • Nanospider laboratory plant Elmarco (semi-technical scale)
  • Small jet electrospinning plant (working temperature up to 220 °C)

TITK has experience with the e-spinning of:

  • Polyvinyl alcohol (PVA), polyethylene oxide (PEO)
  • Cellulose derivatives (trimethylsilyilcellulose, cellulose acetate)
  • Polyacrylonitrile (PAN)
  • Polycarbonate (PC)
  • Polylactic acid (PLA)
  • Gelatin
