Abstract
A coating composition including a compound having a first molecular group or a first combination of atoms, the first molecular group or the first combination of atoms capable of bonding to an oxidizable metal or a metal oxide, and a second molecular group or a second combination of atoms, the second molecular group or the second combination of atoms capable of interacting with a precursor of a polymer so the compound and the polymer are bound together.
