Patent ID: 7722796

Claim:
A method of fabricating continuous nanofibers comprising: providing a column; flowing an extrusion liquid through the column, wherein the extruding liquid defines a viscosity of from about 3,000 to about 15,000 centipoise, and a Reynolds number of from about 0.001 to about 10; flowing a precursor liquid through the extrusion liquid, wherein the flowing precursor liquid defines a diameter of from about 50 to about 100 μm, a viscosity of from about 1 to about 10 centipoise, and a Reynolds number of from about 0.001 to about 1; reducing the diameter of the flowing precursor liquid by extruding the precursor liquid through the extrusion liquid such that the diameter of the precursor liquid is reduced to about 5 μm or less; and forming a continuous nanofiber by solidifying the extruded precursor liquid.
