Abstract
A process for modifying a surface of a metal is provided. The process includes providing a metal surface having a metal oxide, contacting the metal oxide with an organic acid having a hydroxamic acid, a sulphonic acid, or a carboxylic acid functional group, and depositing the organic acid on the surface of the metal oxide for providing a modified metal surface. Modified metal compositions are disclosed having a metal surface or a metal alloy surface having a metal oxide, and an organic acid having a functional group that is deposited onto the surface of the metal oxide forming a self assembled monolayer, multiple monolayers, or a film of a sulphonate, a hydroxamic acid, or a carboxylate with —COOH, —OH and —NHterminal tail groups on the native oxide surface of the metal or the metal alloy.
