Microscopy analysis and production rate data for needleless vertical rods electrospinning parameters

Microscopy analysis and production rate data for needleless vertical rods electrospinning parameters

A multiple vertical rod setup for needless electrospinning was used to fabricate submicron polymer fibers. The design with multiple vertical rods is a new concept for increased production of electrospun fibers. Different geometries and operating conditions are possible. The effects of varying the number of rods in the array have been studied and reported [1]. The goal of this work was a proof o...

Needleless Electrospinning: Developments and Performances

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 Using a Flat Wheel Spinneret

Nanofibers have a wide range of applications, however; the mass production of nanofibers is still an obstacle to wider industrial application. In this paper, a flat wheel was used as a spinneret for production of poly (vinyl) alcohol nanofibers. Electric field comparative analysis was done between the flat wheel and other spinnerets such as a cylinder, disk and ring. It was found the flat wheel...
