Abstract
A method is disclosed for the production of highly diffusive or absorptive metal surfaces. A dendritic crystal structure surface layer of metal is electrodeposited on a substrate, using a bipolar pulse plating technique. This metal surface layer may then be oxidized to provide a highly anti-reflective surface.
Claims6
An article comprising:
- a substrate;
- and
- a highly diffusive metal surface coating on said substrate, said coating including a surface area having a microgeometric ratio greater than about 1000:1, wherein said coating is characterized by a redundant dendritic crystal growth pattern.
Dependencies are inferred from the claim text.
