Electrospinning and Electrospun Nanofibers

Electrospun Metallic Nanofibers Fabricated by Electrospinning and Metallization

Electrospinning of nanofibers from non-polymeric systems: electrospun nanofibers from native cyclodextrins.

Electrospinning of nanofibers from non-polymeric systems is rather challenging, yet in this study, we have successfully performed electrospinning of nanofibers from two of the native cyclodextrins (CDs); α-CD and β-CD. Electrospinning was carried out for highly concentrated solutions of α-CD (120% up to 160%, w/v) and β-CD (120% up to 150%, w/v) in basic aqueous system. At optimal concentration...

Electrospun Nitrocellulose and Composite Nanofibers

Electrospinning was applied to nitrocellulose (NC) solutions  in DMF, DMSO  and  Ethyl  methyl  keton  to  obtain  NC  nanofibers. Electrospraying  process  was  observed  when  DMF  was  used  as solvent.  In  comparison  to NC/DMF, NC/DMSO  solution  resulted  in the  formation  of  a  coating  film  as  indicate  by  SEM.  Two  different electrospun  nanofibers,  smooth  nanofibers  wit...

Modeling Electrospinning of Nanofibers

A fast discrete model for the simulations of thin charged jets produced during the electrospinning process is derived, based on an efficient implementation of the boundary element method for the computation of electrostatic interactions of the jet with itself and with the electrodes. Short-range electrostatic forces are evaluated with slender-body analytical approximations, whereas a hierarchic...

Electrospun light-emitting nanofibers.

We have electrospun light-emitting nanofibers from ruthenium(II) tris(bipyridine)/polyethylene oxide mixtures. The electroluminescent fibers were deposited on gold interdigitated electrodes and lit in a nitrogen atmosphere. The fibers showed light emission at low operating voltages (3-4 V), with turn-on voltages approaching the band gap limit of the organic semiconductor. Because of the fiber s...
