  • Patent number: 10138574
    Abstract: A method and an apparatus for fabricating nanofibrous articles is disclosed. The method may include providing a double-walled nozzle with an inner tube coaxially disposed within an outer tube. In addition, the double-walled nozzle is secured in front of a collector and an electrical field is applied between a tip of the double-walled nozzle and the collector. The method further includes preparing a spinning solution by dissolving a polymer in a solvent, mixing a vapor stream of the solvent with a stream of a pressurized gas with a predetermined ratio to obtain a pressurized solvent/gas stream feeding the spinning solution through the inner tube of the double-walled nozzle, and concurrently feeding the pressurized solvent/gas stream through the outer tube of the double-walled nozzle. The spinning solution and the pressurized solvent/gas stream may concurrently be discharged from the double-walled nozzle and drawn toward the collector being collected as nanofibrous articles on the collector.
