Abstract

A method of forming a polymer-metal nanocomposite (PMNC) material with a substantially uniform dispersion of metal particles includes forming a composite solid preform by mixing a blend of micrometer-sized metal particles and polymer particles and subjecting the mixture to compression followed by sintering. The composite solid preform is drawn through a heated zone to form a reduced size fiber. The reduced size fiber is cut into segments and a next preform is formed using the bundle of the segments. The next preform is then drawn through the heated zone to form yet another reduced size fiber. This reduced size fiber may undergo one or more stack-and-draw operations to yield a final fiber having substantially uniform dispersion of nanometer-sized metal particles therein.
