METHOD FOR MANUFACTURING NANOSTRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a structure which is regulated in a wide area and can be applied to electromagnetic devices such as an optical device and a magnetic device in a simple process by removing visible scratches appearing on a high purity aluminum plate to obtain a mirror surface and then anodizing the surface to improve the surface flatness of the anodized nanostructure. SOLUTION: The method for manufacturing a nanostructure having micropores on the surface is carried out by subjecting an aluminum substrate having ≥99.9% purity to at least mechanical polishing to obtain ≤0.1 μm arithmetic average roughness Ra and ≥60% surface gloss, and then anodizing.
