A new process called Forcespinning™ has been developed to make nanofibers from a wide range of materials. This new method uses centrifugal force, rather than electrostatic force as in the electrospinning process. The Forcespinning™ method uses either solutions or solid materials that are solution or melt spun into nanofibers. Key parameters to control the geometry and morphology of the nanofibers include rotational speed of the spinneret, collection system and temperature. Orifices of the spinneret can have arbitrary geometric shapes to provide corresponding cross-section of nanofibers. The Forcespinning™ method has been successfully used to make nanofibers of poly-ethylene oxide, poly-lactic acid, bismuth, polypropylene, acrylonitrile-butadiene-styrene, polyvinyl pyrrolidone, and polystyrene among others.
