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.
