US Patent 7066998 -Surface Enhanced by Nanoparticles
http://www.freepatentsonline.com/7066998.pdf
Coating films may provide several useful properties in a variety of applications including drying, anti-soiling, glossiness, color, and smoothness control. Typically paints and varnishes have been used for such films but the inventors of this patent have found nanoparticle films with a low water content provide improved properties. Claims 1 and 13 read:
1. A surface coating film for at least partially covering a surface, said coating film comprised of a plurality of nonphotoactive nanoparticles which are present in an amount less than 3 microgram/square cm of the area of the surface.
13. A surface coating film for at least partially covering a surface, said coating film comprised of a plurality of nonphotoactive nanoparticles and water, said film having a water content of less than or equal to about 4%.
