Abstract:
Electrospinning nozzles include novel constructs for providing spinning pores that define the origin of jets of fiber-forming media. In some embodiments, a film covers relatively large holes in a nozzle body and provides spinning pores aligned with such large holes. In some embodiments, conductive tubes are secured at or about relatively large holes in a nozzle body and provide spinning pores fluidly communicating with fiber-forming media at such large holes. In yet other embodiments, nozzle bodies are provided with circular or semi-spherical surfaces having a plurality of spinning pores.
