Electrospinning is a process of creating nanofibers
from a liquid polymer solution. When a high
voltage (5 to 30KV DC) is applied to a polymeric
solution, the charged solution is pulled by
electrostatic forces and becomes attracted to a
grounded collection plate. When enough charge
is introduced to overcome the surface tension of the
polymer, a taylor cone forms and a fine jet ejects
from its surface toward the collection plate.
Parametric Studies
There are several parameters of the
electrospinning apparatus that can be adjusted to
tune the process.
1. Polymer properties: (Viscosity, concentration of
solute to solvent, type of polymer and solvent)
2. Power source properties: (Voltage applied, distance
between collection plate and polymer)
3. Collection plate types (moving, stationary, multiple
plates)
4. Temperature, humidity, atmospheric pressure |
