Preparation of polycrystalline tungsten nanofibers by needleless electrospinning

Upward Needleless Electrospinning of Nanofibers

Polyacrylonitrile (PAN) nanofibers were prepared by a needleless electrospinning method using three rotating fiber generators, cylinder, disc and coil. The effects of the spinneret shape on the electrospinning process and resultant fiber morphology were examined. The disc spinneret needed the lowest voltage to initiate fiber formation, followed by the coil and cylinder. Compared to cylinder, th...

Needleless Electrospinning of Nanofibers With a Conical Wire Coil

Fabrication of Magnetic Nanofibers by Needleless Electrospinning from a Self-Assembling Polymer Ferrofluid Cone Array

Magnetic nanofiber has been widely applied in biomedical fields due to its distinctive size, morphology, and properties. We proposed a novel needleless electrospinning method to prepare magnetic nanofibers from the self-assembling "Taylor cones" of poly(vinyl pyrrolidone) (PVP)/Fe₃O₄ ferrofluid (PFF) under the coincident magnetic and electric fields. The results demonstrated that a static PFF R...

Needleless Electrospinning: Developments and Performances

Preparation and characterization of ZnS:Cu/PVA composite nanofibers via electrospinning

ZnS:Cu/Poly(vinyl alcohol) (PVA) composite nanofibers have been successfully prepared by electrospinning technique. The formation of ZnS: Cu/PVA nanofibers were carried out by reacting H2S with Zn(AC)2:Cu/PVA nanofibers, which were electrospun from the mixture aqueous solution of Zn(Ac)2, Cu(Ac)2 and PVA. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray-diffr...
