Title: Electrostatic Coating with Heavy Metal Nanoparticles by Intrinsic Particle to Surface Interaction


Invention: The technology is a novel electroless deposition technique to form a thin layer of heavy metal on non-traditional substrates such as glass, plastic, and thermal silica.


Background: Electroless plating is prominent in engineering to create a homogeneous and uniform coating on complex shaped items to conduct electricity. Coating non-metallic products is more difficult, but substrates such as plastic have the advantage of higher corrosion resistance and lower weight. In addition, electroless plating can be used for aesthetic purposes such as chrome plating on vehicles.



  • Aviation and aerospace
  • Automotive
  • Chemical processing



  • Can deposit the following heavy metals: gold, platinum, iridium, osmium, rhenium, tungsten, tantalum, and halfium
  • Can deposit on thermal silica, glass, metals, metal oxides, and plastics
  • Does not rely on an electric current and uses the charged surface of the nanoparticles and alteration of the substrate’s surface chemistry
  • Consists of a uniform, homogeneous layer of metal (~3nm-1500nm)
  • Electroless plated coatings are less porous and protect against corrosion
