A review on polymer nanofibers by electrospinning and their applications in nanocomposites

Electrospinning: a fascinating fiber fabrication technique.

Electrospinning is a highly versatile method to process solutions or melts, mainly of polymers, into continuous fibers with diameters ranging from a few micrometers to a few nanometers. This technique is applicable to virtually every soluble or fusible polymer. The polymers can be chemically modified and can also be tailored with additives ranging from simple carbon-black particles to complex species such as enzymes, viruses, and bacteria. Electrospinning appears to be straightforward, but is a rather intricate process that depends on a multitude of molecular, process, and technical parameters. The method provides access to entirely new materials, which may have complex chemical structures. Electrospinning is not only a focus of intense academic investigation; the technique is already being applied in many technological areas.

The effect of processing variables on the morphology of electrospun nanofibers and textiles

Electrospinning is a process by which submicron polymer fibers can be generated through use of an electrostatically driven jet of polymer solution. Use of electrospun nanofibers in electronic, biomedical, and protective clothing applications often involves the incorporation of some sort of functionalized particulate (i.e. carbon nanotubes, activated carbon, clay silicates, etc.). The current work uses conventional and high speed imaging techniques to study the motion of particles in the linear portion of electrostatically driven jets of Polyethylene oxide/water solutions. Observation of the motion of carbon particles using conventional video reveals the presence of eddy currents in the meniscus from which the jet originates. High-speed video of the motion of urethane particles in the liquid jet has been used to measure jet velocities, which range from 1-2 meters/second depending on initial processing conditions. The effect of solution viscosity, field strength, and flow rate on jet velocity and shear rate have implications for the scale up of the electrospinning process and are discussed in detail.
