Abstract:
1. A coated substrate having an organometallic film deposited thereon; in which the substrate has oxide and/or hydroxyl groups that are inherent on the substrate surface or form such groups on exposure to ambient environment; the organometallic film being a polymeric metal oxide having unreacted hydroxyl and alkoxide groups having the structure: where M is a metal, R is an alkyl group containing from 1 to 30 carbon atoms; x+y+z=V, the valence of M; x is at least 1, y is at least 1, z is at least 1; x=V−y−z; y=V−x−z; z=V−x−y; n is from 2 to 1000 and being covalently bonded to the substrate surface through reaction of the surface oxide and/or hydroxyl groups with the alkoxide and hydroxyl groups associated with the polymeric metal oxide.
