Abstract

A method for forming an inorganic or hybrid organic/inorganic layer on a substrate, which method comprises vaporizing a metal alkoxide, condensing the metal alkoxide to form a layer atop the substrate, and contacting the condensed metal alkoxide layer with water to cure the layer is disclosed.

Claims

1. A method for forming an inorganic or hybrid organic/inorganic layer on a substrate, which method comprises:

vaporizing a metal alkoxide;

condensing the metal alkoxide to form a layer atop the substrate; and

contacting the condensed metal alkoxide layer with water to cure the layer.

3. The method of claim 1, further comprising exposing the inorganic or hybrid organic/inorganic layer to a heat treatment.

7. The method of claim 1, comprising contacting the metal alkoxide layer with liquid water.

8. The method of claim 1, comprising contacting the metal alkoxide layer with water vapor.

9. The method of claim 8, comprising contacting the metal alkoxide layer with a plasma containing water vapor.

10. The method of claim 1, wherein the metal alkoxide comprises an alkoxide of aluminum, antimony, arsenic, barium, bismuth, boron, cerium, gadolinium, gallium, germanium, hafnium, indium, iron, lanthanum, lithium, magnesium, molybdenum, neodymium, phosphorus, silicon, sodium, strontium, tantalum, thallium, tin, titanium, tungsten, vanadium, yttrium, zinc, zirconium, or a mixture thereof.

11. The method of claim 10, wherein the metal alkoxide comprises an alkoxide of titanium, zirconium, silicon, aluminum, tantalum, barium, tin, indium, zinc, gallium, bismuth, magnesium, strontium, boron, cerium, hafnium, neodymium, lanthanum, tungsten, or a mixture thereof.

12. The method of claim 11, wherein the metal alkoxide comprises tetra(ethoxy) titanate, tetra(isopropoxy) titanate, tetra(n-propoxy)titanate, polydimethoxysiloxane, methyltriacetoxy silane, tetra(n-propoxy) zirconate, tetra(n-butoxy) zirconate, or a mixture thereof.

13. The method of claim 10, wherein the metal alkoxide comprises a trialkoxysilane.

25. A film comprising at least one inorganic or hybrid organic/inorganic layer formed by the method of claim 1.

26. The film of claim 25, wherein the inorganic or hybrid organic/inorganic layer provides an article with antireflection properties.

27. The film of claim 25, further comprising at least one additional layer that in combination with the hybrid organic/inorganic layer provides an article with anti-reflective properties.

28. The film of claim 25, further comprising at least one additional layer that in combination with the hybrid organic/inorganic layer provides an article with color-shifting properties.

30. An ophthalmic lens comprising the film of claim 27.

31. A security device comprising the color shifting article of claim 28.

32. The device of claim 31 comprising an image.

16. A method for forming a hybrid organic/inorganic layer on a substrate, which method comprises:

vaporizing a metal alkoxide;

vaporizing an organic compound;

condensing the vaporized alkoxide and vaporized organic compound to form a layer atop the substrate; and

curing the layer.

18. The method of claim 16, wherein the vaporized alkoxide and vaporized compound are vaporized separately and mixed in the vapor phase before condensing atop the substrate.

19. The method of claim 16 wherein the alkoxide and the organic compound are vaporized together.

21. The method of claim 16, wherein the organic compound comprises an alcohol, carboxylic acid, ester, acid anhydride, acetyl halogen, thiol, or amine.

22. The method of claim 21, wherein the ester comprises an acrylate.

23. The method of claim 22, wherein the acrylate is cured simultaneously with the metal alkoxide curing.

24. The method of claim 22, wherein the acrylate and metal alkoxide are cured separately.

33. A film comprising at least one hybrid organic/inorganic layer formed by the method of claim 16.

34. The film of claim 33, wherein the hybrid layer comprises an acrylate polymer.

35. The film of claim 33, further comprising at least one additional layer that in combination with the hybrid organic/inorganic layer provides an article with anti-reflective properties.

36. The film of claim 33, further comprising at least one additional layer that in combination with the hybrid organic/inorganic layer provides an article with color-shifting properties.

37. An ophthalmic lens comprising the antireflection film of claim 35.

38. A security device comprising the color shifting article of claim 36.
