Processing of superhydrophilic, infrared transmissive, anti-reflective nanostructured surfaces

Abstract

A method for producing nanostructured, hydrophilic, transmissive, anti-reflective surfaces is described. The method for providing a hydrophilic surface includes steps of providing a substrate that is transmissive in at least one wavelength in the infrared to ultraviolet range of the electromagnetic spectrum and comprises at least one surface including nanostructures of a size smaller than the at least one wavelength; and functionalizing the at least one surface with hydroxyl groups thereon. This method provides devices having excellent transmittance and anti-reflectance properties and which are resistant to seawater.
