Electrospinning (to form ultrafine polymer fibers)

Electrospinning uses electrical charges to form fibers. Standard setups for electrospinning include metallic needles with a pump, a high-voltage power supply, and a grounded collector. The elongation and bending through a series of processes results in the fabrication of uniform fibers with nanometer-scale diameters.

Trek’s amplifiers are used to provide high voltages (typically 10kV to 20 kV) to generate sufficient surface charge to overcome the surface tension in a drop of polymer fluid.  This results in the ejection of a fluid jet that is drawn down by acceleration to a grounded collector.  The diameters of the electrospun fibers are at least one order of magnitude smaller than those made by conventional extrusion techniques.

Trek products that are used in the Electrospinning process are the Models:  610E, 20/20C, P0621

Electrospraying

Trek’s amplifiers are used to control the electric field strength to create the electrospray; this technique atomizes a droplet from a capillary needle, drawn out by an electric field.

Trek products used in the Electrospraying process are the Models:  20/20C, 10/10B-HS
