Outline of Final Research Achievements

Highly ordered nanolens array was fabricated via novel self-ordering anodizing. Highly ordered aluminum dimple arrays were formed on an aluminum substrate via selenic and etidronic acid anodizing and subsequent anodic oxide dissolution. The nanostructured aluminum surface led to bright structural coloration with a rainbow spectrum. The shape of the dimple arrays were transferred to a mercapto-ester ultra-violet curable polymer via polymer replications using a nanoimprinting technique. The nanostructured polymer surfaces also exhibited structural coloration based on the periodic nanostructure.
