Abstract

A coated transparency includes: a transparency; a base layer on the transparency, the base layer comprising at least one selected from an organic compound, an organosilicon compound, and a polysiloxane compound; a metal layer physically contacting the base layer; and a metal oxide layer on the metal layer, the metal oxide layer comprising aluminum doped zinc oxide (AZO).

Claims

1. A coated transparency comprising:

a transparency;

a base layer on the transparency, the base layer comprising at least one selected from an organic compound, an organosilicon compound, and a polysiloxane compound;

a metal layer physically contacting the base layer; and

a metal oxide layer on the metal layer, the metal oxide layer comprising aluminum doped zinc oxide (AZO).

2. The coated transparency of claim 1, wherein the metal layer is substantially free of silver.

3. The coated transparency of claim 1, wherein the transparency is selected from the group consisting of an aircraft canopy, an aircraft windshield, and an aircraft window.

4. The coated transparency of claim 1, wherein the metal oxide layer has a thickness in a range of about 10 nm to less than 200 nm.

5. The coated transparency of claim 1, wherein the metal oxide layer has a thickness in a range of greater than 20 nm to less than 180 nm.

6. The coated transparency of claim 1, wherein the base layer comprises a material selected from the group consisting of polyepoxides, polyacrylates, polyurethanes, polysiloxanes, and combinations thereof.

7. The coated transparency of claim 1, wherein the metal layer has a thickness in a range of about 5 to about 20 nm.

8. The coated transparency of claim 1, further comprising a tie layer between the transparency and the base layer.

9. The coated transparency of claim 1, further comprising a topcoat on the metal oxide layer.

10. The coated transparency of claim 9, wherein the topcoat comprises polyurethane.

11. The coated transparency of claim 9, wherein the topcoat physically contacts the metal oxide layer.

12. The coated transparency of claim 9, further comprising a topcoat tie layer between the topcoat and the metal oxide layer.

13. The coated transparency of claim 12, wherein the topcoat tie layer is electrically conductive.
