Fine fibers made from room temperature crosslinking

A method of making a fine fiber, the method comprising:

• providing a polymer component, wherein the polymer component comprises a 4-vinyl pyridine-containing polymer;
• providing a solvent;
• providing an epoxy, wherein the epoxy is at least difunctional;
• and
• combining the polymer component, the solvent, and the epoxy to form a composition and forming a plurality of fibers out of the composition, such that the entirety of each fiber is prepared from the composition without increasing the temperature of the composition above 80° C.

A method of making a coated fine fiber, the method comprising:

• providing a polymer component, wherein the polymer component comprises a 4-vinyl pyridine-containing polymer;
• providing a solvent that does not complex with 4-vinyl pyridine;
• providing an epoxy, wherein the epoxy is at least difunctional;
• providing a fiber;
• and
• combining the polymer component, the solvent, and the epoxy to form a composition and coating the fiber with the composition.
