Electrospinning carbon nanotube polymer composite nanofibers

The unique and exceptional physical properties of carbon nanotubes have inspired their use
as a filler within a polymeric matrix to produce carbon nanotube polymer composites with
enhanced mechanical, thermal and electrical properties. A powerful method of synthesising
nanofibers comprising these polymer composites is electrospinning, which utilises an applied
electric stress to draw out a thin nanometer-dimension fiber from the tip of a sharp conical
meniscus. The focussing of the flow due to converging streamlines at the cone vertex then
ensures alignment of the carbon nanotubes along the fiber axis, thus enabling the anisotropic
properties of the nanotubes to be exploited. We consider the work that has been carried out to
date on various aspects encompassing preprocessing, synthesis and characterisation of these
electrospun polymer composite nanofibers as well as the governing mechanisms and associated
properties of such fibers. Particular attention is also dedicated to the theoretical modelling
of these fiber systems, in particular to the electrohydrodynamic modelling of electrospinning
polymer jets.
