US Patent 7482421 - Self-healing anti-corrosive nanoparticle coating

This patent from the University of Cincinnati teaches a superprimer based on nanoparticles. Claim 1 reads:

1. A hydrophilic composition capable of coating a substrate and curing to provide a hydrophobic film inhibiting corrosion, the composition comprising:

a bis-silane comprising between about 15 percent by weight to about 40 percent by weight of the composition;

a water soluble or dispersible polymer;

a water soluble solvent; and

nanoparticles having a mean particle size of ranging between about 0.01 nanometers to about 500 nanometers.
