Electrospinning is a useful tool for producing fine fibers of about 10
nanometers to 10 microns in diameter from both natural and synthetic polymers.
Historical developments, theory, and the types equipment used to produce aligned and
non-aligned fibres in electrospinning are discussed. Collector composition or
substrates, dimension of the collector, electrospinning materials and configurations of
nozzle in electrospinning are discussed with their respective importance. The
electrospinning process is influenced by the following solution parameters like
viscosity, polymer molecular weight, polymer concentration, surface tension, polymer
solution conductivity or surface charge density, rate of evaporation of solvents,
dielectric constant and vapour pressure. Voltage, needle tip to collector distance, feedrate,
collector material, electrospinning setup, diameter of needle orifice, environmental
(ambient) parameters like temperature, humidity, type of atmosphere and pressure also
determine electrospun fiber size and morphology.
