Abstract
A metal or metal alloy including a region with hierarchical micro-scale and nano-scale structure shapes, the surface region is super-hydrophobic and has a spectral reflectance of less than 30% for at least some wavelengths of electromagnetic radiation in the range of 0.1 μm to 10 μm. Methods for forming the hierarchical micro-scale and nano-scale structure shapes on the metal or metal alloy are also described.
Claims1
A metal or metal alloy comprising at least one surface region including a plurality of micro-scale structure shapes having a depth or height in the range of 0.1 to 500 μm and a plurality of nano-scale structure shapes having at least one dimension that is less than 1 μm, wherein the at least one surface region is super-hydrophobic having a water contact angle of 150° or greater, wherein the at least one surface portion has a spectral reflectance of less than 60% for at least some wavelengths of electromagnetic radiation in the range of 0.1 μm to 500 μm.
