Abstract:
A method for forming a substrate with a multi-layered, flexible, and anti-scratch metal oxides protective coating being deposited onto the substrate is provided in the present invention, wherein the top most layer of the coating comprises Al2O3 or a mixture thereof such that the top most layer acts as an anti-scratching layer. The multi-layered, flexible and anti-scratch metal oxides protective coating also retains the flexibility of the underlying substrate.
