US Patent 8003165 - Electroless plating of catalyst for nanotube growth


This patent from Applied Nanotech has priority going back to 2001 and includes some basic claims for growing carbon nanotubes based on electroless plating of the catalyst. Claim 1 reads:

1. A method comprising the steps of:

coating nanoparticles with a catalyst, wherein the catalyst has a property that promotes carbon nanotube growth thereupon, wherein the coating step uses an electroless plating bath process to coat the catalyst onto the nanoparticles;

depositing the nanoparticles coated with the catalyst onto a substrate; and

growing carbon nanotubes on the nanoparticles.
