Abstract
Moth-eye surfaces can prevent reflection with minute unevenness structure of nanometer size. A nano-imprinting process, which generates minute patterns of polymers using a mold, is a promising candidate for a high-throughput patterning process. In the present report, first of all, I describe the nano-imprinting processes based on the highly ordered anodic porous alumina. Anodic porous alumina, which is formed by the anodization of Al in acidic solution, is a typical naturally occurring ordered material. The Anodic porous alumina can be formed even on the curved surface. We have been researching a continuous manufacturing process of the moth-eye surfaces on polymer films with the roll molds. Second, I mention optical characteristics of the moth-eye surfaces. Third, I report multi-functionalities of the moth-eye surfaces.
