“…We now have successfully developed the setups of electric-assisted centrifugal spinning, air-assisted centrifugal spinning, and melting centrifugal spinning . By using these setups, we not only prepared ultrafine fibers from polyester (PET), polyvinylpyrrolidone (PVP), polyoxyethylene (PEO), and regenerated silk but also created highly porous ethyl cellulose fibers, alginate-rich nanofibers, and grape-tree-like and porous PTFE fibers . These fibers expressed high specific surface area, excellent solution absorption, and super-hydrophobic properties and are therefore particularly suitable for application in filtration, wound dressing, and oil/water separation.…”

In this research, centrifugally spun ultrafine composite starch/polyvinyl alcohol (ST/PVA) fibers with high water stability were prepared by cross-linking with a mixture of glutaraldehyde and formic acid in the form of vapor phase. The effect of cross-linking temperature combined with time on the water stability, crystal structure, and thermal properties of fibers was investigated to obtain the optimum parameters. On this basis, we further prepared Ag-loaded ST/PVA fibers with different contents of nano silver. The structure and properties of Ag-loaded fibers, which cross-linked under the optimum parameters, were analyzed. As a result, the Ag-loaded fibers exhibited excellent water stability and mechanical properties and possessed inhibition zone diameters of 3 and 2 mm to Escherichia coli and Staphylococcus. aureus, respectively. The antibacterial property of the Ag-loaded ST/ PVA fibers provided a new route for developing less costly antibacterial fiber materials in the future.

“…On the other hand, the electrospinning process has a low fiber yield of about 0.1 grams/hour, thus limiting the scaling up and productivity of the electrospinning process for commercial electrode applications. Centrifugal spinning is another method that has been recently employed to produce nanofibers as electrode for LIBs [42,43]. However, the centrifugal spinning method cannot be used to produce fibers at high rotational speeds and presently it has no capacity of melt spinning [24] , [44][45][46][47] , [48,49].…”

Forcespinning: A new method for the mass production of Sn/C composite nanofiber anodes for lithium ion batteries

et al. 2016

The development of nanostructured anode materials for rechargeable Lithium-ion Batteries has seen a growing interest. We herein report the use of a new scalable technique, Forcespinning (FS) to produce binder-free porous Sn/C composite nanofibers with different Sn particle size loading. The preparation process involves the FS of Sn/PAN precursor nanofibers and subsequently stabilizing in air at 280 o C followed by carbonization at 800 o C under an inert atmosphere. The Sn/C composite nanofibers are highly flexible and were directly used as binder-free anodes for lithiumion batteries. The produced Sn/C composite nanofibers showed an improved discharge capacity of about 724 mAhg-1 at a current density of 100 mAg-1 for over 50 cycles compared to most nanofiber electrodes prepared by electrospinning and centrifugal spinning. The FS method clearly produces Sn/C nanofiber composite electrodes that have a high specific capacity and excellent cyclic performance, owing to the unique structure and properties of the nanofibers. The FS technology is thus a viable method for the large scale production of nano/micro fibers for battery electrodes, separators, and other applications. To the best of our knowledge, this is the first time to report results on the use of Forcespinning technology to produce composite nanofiber anodes for lithiumion batteries.

“…Only a handful of polymers such as poly(butylene terephthalate) (PBT), polypropylene (PP), polycaprolactone (PCL), and poly(ethylene terephthalate) (PET) have been reported to date for RJS of polymer melts,. Polymer solutions are more widely studied in RJS, with fibers being successfully spun from polyamide 6 (PA6), poly(ethylene oxide) (PEO), PCL, poly( L ‐lactic acid) (PLLA), and polyacrylonitrile (PAN) solutions.…”

The recently popularized method of rotary jet spinning (RJS) or centrifugal spinning is investigated to evaluate the rheological limitations of polymer solutions and melts to optimal spinnability. The influence of Newtonian or non-Newtonian behavior of the polymer on spinnability is discussed. We observe that highly viscous polymers tend to block the die channels within a rotary jet spinneret and therefore suggest the use of relatively low Newtonian viscosities of between 1 and 10 Pa s for optimal fiber production. Computational fluid dynamics simulations are used in conjunction with experimental data to establish important processing parameters, such as typical shear rates in the device and optimal polymer melt or solution viscosities. A theoretical model for RJS is compared to measured fiber diameters. The comparison shows that although fiber diameters can be estimated very roughly in the case of polymer solutions, the prediction of fiber diameter in the case of polymer melts require further modeling work.
