1. A self-cleaning material that is responsive to exposure to light comprising:
- a substrate having a first surface; and
a self-cleaning layer of longitudinally aligned nanotube structures formed on the first surface of the substrate, wherein longitudinal axes of the nanotube structures are parallel to each other and form a non-zero acute orientation angle with respect to an axis normal to the first surface such that the self-cleaning material changes states responsive to the exposure to light based at least in part on an angle of incidence of the light and the orientation angle.

Abstract
A self-cleaning material is generally described that may include a substrate having a first surface. A self-cleaning layer of aligned nanotube structures may be formed on the first surface of the substrate, where absorption of light by the nanotube structures may cause a change in state of the self-cleaning material based on an angle of incidence of the light and an orientation vector corresponding to the layer of aligned nanotube structures.

7. 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 of longitudinally aligned nanotube structures formed on the first surface of the substrate, wherein first longitudinal axes of the nanotube structures of the first self-cleaning layer are parallel to each other and form a first non-zero acute orientation angle with respect to an axis normal to the first surface and arranged such that the first self-cleaning layer changes states responsive to the exposure to light based at least in part on the first orientation angle; and a second self-cleaning layer of longitudinally aligned nanotube structures formed on the second surface of the substrate, wherein second longitudinal axes of the nanotube structures of the second self-cleaning layer are parallel to each other and form a second non-zero acute orientation angle with respect to an axis normal to the second surface and arranged such that the second self-cleaning layer changes states responsive to the exposure to light based at least in part on the second orientation angle. - View Dependent Claims (8, 9, 10, 11, 12)

13. A self-cleaning material that is responsive to exposure to light comprising:
a first self-cleaning layer of longitudinally aligned titanium dioxide nanotube structures formed on a first surface of a glass substrate, wherein first longitudinal axes of the titanium dioxide nanotube structures of the first self cleaning layer are parallel to each other and form a first non-zero acute orientation angle with respect to an axis normal to the first surface such that absorption of light by the titanium dioxide nanotube structures of the first self cleaning layer induces a photo-induced hydrophilic state of the first self-cleaning layer of aligned titanium dioxide nanotube structures based at least in part on a first angle of incidence of the light and the first orientation angle. - View Dependent Claims (14, 15, 16, 17)
