Advantages
- More cost-effective than existing chemical vapor deposition (CVD) methods
- Low-temperature process
- Adaptable to large scale processes
- Compatible with a variety of different substrates
Technology
The process of this invention produces nanodiamond surface coatings using a linker species to covalently bond fluorinated diamond crystallites to a surface. The technique can be applied to surfaces such as ceramics, glass, polymers, semiconductors, and metals. Using standard wet chemistry techniques, the process avoid the sophisticated and costly equipment (vacuum chamber, furnace, heater or plasma generator, etc.) required by conventional vapor deposition techniques. Additionally, this technique can be applied on a large scale and for coating large areas on a variety of different substrates.
Potential Applications
- Nano-electromechanical systems (NEMS)
- Micro-electromechanical systems (MEMS)
- Field emission devices and sensors
- Chemically resistant coatings for tools, etc.
