Abstract
The disclosure relates to hydrophobic coatings for oxidized surfaces and methods of producing the same. Such coatings may be produced by applying a compound of the general formula AXn or A(R1)mXn to an oxidized surface followed by a nucleophilic compound of the general formula DR2. The processes may result in a hydrophobic unreactive organic coating that sterically inhibits access to the underlying oxidized surface or reactive groups. In selected embodiments, the hydrophobic coating may form a monolayer.
Claims16
A method of passivating an oxidized surface, comprising the steps of:
- applying an active species comprising a compound of a first constituent and a second constituent to the oxidized surface, the first constituent being a metal, semimetal, transition metal, or a ceramic, and the second constituent being a reactive group, so that the first constituent covalently bonds with the oxidized surface and the reactive group is exposed;
- and
- then reacting a nucleophilic molecule to displace the exposed reactive group, and to covalently bond the nucleophilic molecule with the first constituent.
