US Patent 7858186 - Fluorinated nanodiamond

http://www.freepatentsonline.com/7858186.html

Chemical vapor deposition (CVD) has commonly been used to form diamond thin films and coatings but requires high temperature and cost. This patent from Rice University teaches an alternative technique using nanodiamonds to form coated surfaces. Claim 1 reads:

1. A nanodiamond coated surface comprising:

a) a substrate surface; and

b) fluorinated nanodiamond crystallites,

wherein the fluorinated nanodiamond crystallites are covalently bound to the substrate surface via a silane linker species; and

wherein the silane linker species further comprises an amine that is covalently bound to the fluorinated nanodiamond crystallites.
