Abstract:
A low reflectivity coating ( 20 ) is formed of a layer of carbon nanostructures ( 20 ) over a contact surface ( 14 ) of a substrate ( 1 0 ), from a spray incorporating the carbon nanostructures in suspension in a solvent. The carbon nanostructure layer provides a very low reflectivity coating which may be further enhanced by etching the outer surface of the coating. The layer may be etched for reduced reflectivity. Very low reflectivity coatings have been achieved.

Claim (Index 1):
A method of coating a substrate with carbon nanostructures, including the steps of:\n (i) providing a suspension of carbon nanostructures in a solvent; (ii) pre-heating a substrate to a sufficient temperature to cause the solvent to evaporate when the suspension contacts the substrate; and then (iii) spray-coating the suspension onto the substrate; (iv) maintaining the substrate at a sufficient temperature during step (iii) in order to maintain evaporation of the solvent being spray-coated; (v) continuing with steps (iii) and (iv) until a layer of carbon nanostructures has been coated on the substrate with a thickness of at least 2 micrometres; and (vi) plasma etching the coating to reduce film density and create the optical cavities in the coating, adding an optical spacer to the suspension prior to the depositing step in order to create optical cavities in the coating, or a combination thereof.
