Abstract
The present invention provides a dense-coverage, adherent phosphorous-based coating on the native oxide surface of a material. Disclosed phosphorous-based coatings include phosphate and organo-phosphonate coatings. The present invention also provides further derivatization of the phosphorous-based coatings to yield dense surface coverage of chemically reactive coatings and osetoblast adhesion-promoting and proliferation-promoting coatings on the native oxide surface of a titanium material.
Claims48
An adherent, self-assembled phosphorous-based coating layer bonded to the native oxide surface of a material by heating a self-assembled phosphorous-based acid layer formed on the surface thereof until said layer is bonded thereto, wherein said phosphorous-based acid is selected from the group consisting of phosphoric acid and organophosphonic acids.
A method of bonding a layer of a phosphorous-based acid moiety to a titanium oxide surface comprising a coating said oxide surface with a phosphorous-based acid moiety self-assembled layer and heating said coated oxide surface until said self-assembled layer is bonded thereto, wherein said phosphorous-based acid is selected from the group consisting of phosphoric acid and organo-phosphonic acids.
