NANOSTRUCTURED MATERIALS, METHODS, AND APPLICATIONS
First Claim
1. A method for making a non-superhydrophyllic material superhydrophilic (superwetting), comprising the steps of:
- a) providing a non-superhydrophilic material having at least one of a smooth, a roughened, and a pre-structured surface; and
b) processing the surface region of the material using an energy flux comprising at least one of one or more pulses from a suitable energy source and continuous radiation from a continuous energy source, further comprising;
i) creating one or more indentations in the surface, wherein said one or more indentations have a micro-rough surface comprising at least one of protrusions, cavities, spheres, rods, and other irregularly shaped features having heights and/or widths on the order of 0.5 to 100 microns,
further wherein the micro-rough surface has a nano-rough surface comprising at least one of protrusions, cavities, spheres, rods, grooves, and other irregularly shaped features having heights and/or widths on the order of 1 to 500 nanometers.

Abstract
Methods for making a material superwicking and/or superwetting (superhydrophyllic) involving creating one or more indentations in the surface of the material that have a micro-rough surface of protrusions, cavities, spheres, rods, or other irregularly shaped features having heights and/or widths on the order of 0.5 to 100 microns and the micro-rough surface having a nano-rough surface of protrusions, cavities, spheres, rods, and other irregularly shaped features having heights and/or widths on the order of 1 to 500 nanometers. Superwicking and/or superwetting materials having micro-rough and nano-rough surface indentations, including metals, glass, enamel, polymers, semiconductors, and others.

29. A material, comprising:
-
an initially non-superhydrophilic material having at least one of a smooth, a roughened, and a pre-structured surface; and one or more indentations in the surface, wherein said one or more indentations have a micro-rough surface comprising at least one of protrusions, cavities, spheres, rods, and other irregularly shaped features on the order of 0.5 to 100 microns, further wherein the micro-rough surface has a nano-rough surface comprising at least one of protrusions, cavities, spheres, rods, grooves, and other irregularly shaped features on the order of 1 to 500 nanometers. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
