Organometallic films, methods for applying organometallic films to substrates and substrates coated with such films
Organometallic coatings or films, substrates coated with such films and methods for applying the films to the substrates are disclosed. The organometallic film or coating is derived from a transition metal compound containing both halide ligands and alkoxide ligands. Coated articles comprising polymer substrates and adhered to the substrate surface an organometallic film in which the metal comprises halide and alkoxide ligands are also disclosed.
1. An organometallic film formed on a substrate in which the organometallic film comprises a polymeric metal oxide with alkoxide ligands and hydroxyl ligands and halide ligands.
2. The organometallic film of claim 1 in which the metal is selected from Ti, Zr, La, Hf, Ta and W.
3. The organometallic film of claim 2 , which has a different film deposited thereon.
4. The organometallic film of claim 1 having the following structure:
[M(O) x (OH) y (OR) z (Q) w ] n
where M is a metal, R is an alkyl group containing from 1 to 30 carbon atoms; Q is a halide group; x+y+z+w=V, the valence of M; x, y, z and w are at least 1; x=V−y−z−w; y=V−x−z−w; z=V−x−y−w; w=V−x−y−z; and n is greater than 2.
