摘要
A method to apply nano-crystalline diamond onto a selected substrate, comprising preparing a nanodiamond slurry of nanodiamond particles dispersed in a medium; immersing the selected substrate in the nanodiamond slurry for a predetermined period of time; removing the substrate from the slurry; drying the substrate and nanodiamond slurry that is adherent to the substrate with a flow of inert gas whereby the substrate is left coated with a coating of the nanodiamond particles that are adherently held by van der Waals forces; and selecting the medium in which the nanodiamond particles are dispersed to be a chemically functionalized carrier medium that includes a volatile component and an inorganic oxide, the volatile component being selected to evaporate at ambient room temperature or at elevated temperature and atmospheric pressure to leave behind the inorganic oxide.
