Fabrication of Melt Spun Polypropylene Nanofibers by Forcespinning
Melt spinning of polypropylene nonwoven nanofiber mats is demonstrated using Forcespinning The effects of rotational speed and melt flow rate of polymer on fiber diameter were studied. It was observed that melt flow rate of the polymer plays a major role in nanofiber formation and uniformity. Differential scanning calorimetry and X-Ray Diffraction analysis indicate that the crystallinity of nan...
متن کاملTitanium Dioxide Nanofibers through Forcespinning
Titanium dioxide (TiO2) nanofibers with potential applications in the fabrication of dye sensitized solar cells, photocatalysts, gas sensors, and water treatment systems, among others, have been produced at large yield rates utilizing the Forcespinning (FS) technology. This study presents the results of research performed to determine optimal processing parameters to create TiO2 nanofibers at a...
متن کاملMechanical response of melt-spun amorphous filaments
High-speed melt spinning of a cyclo-olefin polymer (COP) and a copolyamide (CoPA) have been performed. Differential scanning calorimetry curves of the resulting monofilaments show that they remain in an amorphous state even after hot drawing. Wide angle x-ray diffraction patterns of undrawn and drawn COP filaments show that although the material remains in an amorphous state, a degree of orient...
متن کاملCOERCIVITY MECHANISM OF MELT-SPUN Sm(Fel1Ti)
Hysteresis loops of randomly oriented grains with uniaxial anisotropy were computed on the basis of an array of 27 Wigner Seitz cells representing crystallites which interact by exchange coupling at the grain boundaries. The computed coercivity increases linearly with increasing interatomic exchange. Using the experimental anisotropy and exchange parameters for Sm(FellTi), we found 1.lo&=1.2 T ...
متن کاملMagnetic properties and synthesis conditions of Nd2Fe23B3 melt-spun alloy
The formation of amorphous and crystalline state of the Nd2Fe23B3 alloy from melt-spun ribbon is presented. The synthesis conditions are investigated combining DSC, X-ray diffraction and thermomagnetic analysis. The thermomagnetic analysis is found to be very useful to optimize the synthesis process. Comparison of these results enables to discuss the thermal stability of both the amorphous and ...
