Abstract

The invention discloses a wide-spectrum extremely-low transmission structure and a preparation method thereof. The wide-spectrum extremely-low transmission structure comprises a substrate, and furthercomprises a nano forest structure directly formed on at least one surface of the substrate, and metal nano particles loaded on the nano forest structure; when only one surface of the substrate is ofa nano forest structure, a metal layer is arranged on the other surface, opposite to the nano forest structure, of the substrate. The structure provided by the invention has the advantages of high stability and high light absorption capability.

Description

technical field [0001] The invention relates to the field of optics, in particular to a wide-spectrum ultra-low transmission structure and a preparation process thereof. Background technique [0002] The wide-spectrum ultra-low transmission structure has a wide range of applications. The usual method is to use a certain method to set graphene, carbon nanotubes, carbon black and other broad-spectrum high-absorption materials on the substrate material to achieve broad-spectrum high absorption of the entire device. . However, there is poor adhesion between these materials and the substrate, and the material is easy to fall off, especially under the action of force, the material is very easy to peel off from the substrate material. Even after wrapping the entire layer of material with a specific film protective layer, the entire layer of material may be damaged due to damage to the film protective layer. In addition, the use of thin-film protective layers can also affect the o...
