Claims
- 1. A UV-protected and oxygen-protected composite, comprising:
- a flexible polymer-containing substrate subject to deterioration by exposure to oxygen and ultraviolet radiation;
- a metal oxide barrier coating having a thickness lying substantially within a range of 500 Angstroms to 10,000 Angstroms comprising silicon oxide formed on the substrate for protecting the substrate from degradation by ultraviolet radiation and oxygen; and
- an intermediate silicon-containing coating for forming oxides in the presence of oxygen to repair breaches in the barrier coating and thereby protect the barrier coating from degradation by oxygen,
- the thickness of said silicon-containing intermediate coating being substantially within the range of 0.001 inch to 0.01 inch.
- 2. The composite of claim 1, wherein the intermediate coating comprises organo-silicone.
- 3. The composite of claim 1, further comprising a coating of adhesion primer formed between the substrate and the silicon-containing coating for increasing the adhesion of the intermediate silicon-containing coating to the substrate.
- 4. The composite of claim 1, wherein the barrier coating comprises a plurality of layers of different materials.
- 5. The composite of claim 4, wherein the barrier coating is an optical filter comprising alternating layers of metal oxides.
- 6. The composite of claim 4, wherein the barrier coating is a stress-controlled optical coating comprising alternating layers of silicon oxide and aluminum oxide.
