Abstract
A method of forming a metal structure. The method comprises providing a dispersion of metal nanoparticles and a solution comprising a transient polymer and solvent. The dispersion of metal nanoparticles and the solution are formed by coaxially electrospinning into a fiber comprising the metal nanoparticles and the transient polymer. The fiber is heated to decompose the transient polymer and form a metallic structure.

A method of forming a metal nanostructure, the method comprising:
- providing a dispersion of metal nanoparticles;
- providing a solution comprising a transient polymer;
- and
- coaxially electrospinning the dispersion of metal nanoparticles and the solution to form a plurality of core-shell fibers, wherein the dispersion of metal nanoparticles forms a fiber core and the transient polymer forms a polymer shell surrounding the fiber core;
- heating the core-shell fiber to form a metallic nanostructure, wherein the heating of the core-shell fiber comprises heating to a first temperature to melt the metal nanoparticles, and then heating the core-shell nanofibers to a second temperature to remove the polymer, the second temperature being higher than the first temperature;
- and
- wherein the metal nanostructure has at least one dimension that is less than 500 nm.
