Abstract
Metallized polymer particle compositions may comprise polymer particles, and a metal coating on an outer surface of at least a portion of the polymer particles. The metal coating comprises a plating metal and overlays a plurality of two-dimensional conductive nanoparticles and a catalyst metal. The metal coating may be formed by at least an electroless plating process conducted in the presence of the catalyst metal. The polymer particles may comprise thermoplastic polymer particles.
