| 摘要 |
The present invention relates to a multi-functional nanofilm using a dual structure and a manufacturing method thereof, which can manufacture a film having broadband transmittance by complexly forming a protruding shape pattern with a moth eye structure and a self-cleaning pattern of a lotus leaf, by comprising: a substrate; a central protrusion which changes the transmittance of light by being formed on the surface of the substrate; and outer protrusions whose height becomes smaller as going to the outer side from the central protrusion. The protrusions whose height becomes smaller as going to the outer side from the central protrusion are positioned in a micrometer unit area in order to form a first transmittance change pattern. The protrusions formed inside the micrometer unit area have a column shape in a nanometer unit and have a size which is reduced in an arc shape as going to the end in order to form a second transmittance change pattern. |
