Synthesis of metal nanoparticle compositions from metallic and ethynyl compounds

A composition made by the process of:

• providing a precursor composition comprising a polymer and a metallic component;
• wherein the polymer has crosslinked ethynyl groups;
• wherein the metallic component is bonded to the polymer, combined with the polymer or combinations thereof;
• and
• heating the precursor composition under conditions effective to produce metal nanoparticles.

A metal nanoparticle composition comprising metal nanoparticles dispersed homogenously in a matrix selected from the group consisting of ethynyl polymer, crosslinked ethynyl polymer, amorphous carbon, carbon nanotubes, carbon nanoparticles, graphite, and combinations thereof, made by a process comprising the steps of:

• providing a precursor composition comprising at least one metallic component and at least one organic component;
• wherein the precursor composition is a liquid or solid at room temperature;
• and
• heating the precursor composition under conditions effective to produce metal nanoparticles.
