1. A self-cleaning material that is responsive to exposure to light comprising:
- a substrate having a first surface and a second surface;
a self cleaning layer disposed on the first surface of the substrate; and
a diffraction grating formed in an exposed surface of the self cleaning layer, wherein the diffraction grating includes a blaze condition that is arranged to enhance absorption of light incident on the exposed surface.

Abstract
A self-cleaning material is generally described that may include a substrate having a first surface and a second surface. A self cleaning layer may be disposed on the first surface of the substrate. A diffraction grating may be formed in an exposed surface of the self cleaning layer, where absorption of light by the self cleaning layer incident on the exposed surface may be enhanced by the diffraction grating in accordance with a blaze condition corresponding to the diffraction grating.

10. A self-cleaning material that is responsive to exposure to light comprising:
-
a substrate having a first surface and a second surface; a first self cleaning layer disposed on the first surface of the substrate, wherein a first diffraction grating having a first blaze condition is formed on a first exposed surface of the first self cleaning layer and arranged to enhance the absorption of light based at least in part on the first blaze condition; and a second self cleaning layer disposed on the second surface of the substrate, wherein a second diffraction grating having a second blaze condition is formed on a second exposed surface of the second self cleaning layer and arranged to enhance the absorption of light based at least in part on the second blaze condition. - View Dependent Claims (11, 12, 13, 14, 15)

16. A self-cleaning material comprising:
-
a first blazed diffraction grating formed in a first surface of the self-cleaning material, wherein absorption of light by the self-cleaning material incident on the first surface is arranged to enter a first photo-induced self cleaning state on the first surface based on a first blaze condition corresponding to the first blazed diffraction grating and a first incident angle of the light with the first surface; and a second blazed diffraction grating formed in a second surface of the self-cleaning material, wherein absorption of light by the self-cleaning material incident on the second surface is arranged to enter a second photo-induced self cleaning state on the second surface based on a second blaze condition corresponding to the second blazed diffraction grating and a second incident angle of the light with the second surface. - View Dependent Claims (17, 18)
