Abstract
Methods of fabricating continuous nanofibers include the steps providing a column, flowing an extrusion liquid through the column, and flowing a precursor liquid through the extrusion liquid, wherein the flowing precursor liquid has a viscosity less than the viscosity of the extrusion liquid. The method further includes reducing the diameter of the flowing precursor liquid by extruding the precursor liquid through the extrusion liquid, wherein the diameter of the precursor liquid is reduced by a factor of at least 5, and forming a continuous nanofiber by solidifying the extruded precursor liquid.
