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.
