  • Publication number: 20230038283
    Abstract: Electrospinning (ES) provides the technical community with a readily available method to produce polymer fibers ranging from nanoscale to microscale. Here, we present a novel “hybrid electrospirming apparatus,” whereby, modifications to a melt electrospinner have allowed fabrication of core-sheath fibers with polymer sheaths and solution-based cores. These modifications include a split polymer melt heating block, coaxial block spinneret equipped with heaters and multiple feed ports for core and sheath material, and a wiring system for heat which requires multiple switches for safety and on-demand heat activation. Successful demonstration of coaxial fiber fabrication is demonstrated using polycaprolactone-polyethylene oxide blend shell and fluorescent gelatin core materials.
