NANO STRUCTURE AND MANUFACTURING THEREOF

摘要

A nano structure is provided to embody a more beautiful color than ordinary pigments, and be surface-colored at low cost and in a simple manner. A method for manufacturing a nano structure for coloring the surface thereof includes the steps of: forming a first metal layer on the upper part of the surface; anodizing the metal layer to form a nano hole array structure(20) in which nano holes are formed in an array shape at regular intervals; forming a second metal layer(30) on the at least upper parts of the nano holes; and further forming a protective layer on the upper part on which the second metal layer is formed. The pitch(D) between nano holes is 20-500 nm.
