Embodiment Construction

[0029] The following is a detailed explanation of the present invention.

[0030] like figure 1 Show, a kind of ultraviolet-visible-infrared full-band absorber consists of a number of ultraviolet-visible-infrared full-band reduction of the bonding film system 2 and the base of the base Essence

[0031] The base 1 material is selected from midfield infrared absorption materials. You can choose glass materials such as K9, melting quartz, floating glass, etc. You can also choose organic glass (acrylic, PMMA, polymethyl acrylic methyl ester, etc.), CR-39 (polypropylene basis two two 2 Glycolic carbonate), PC (polyteyl carbonate), PS (styrene) and other organic polymer materials.

[0032] UV-Visible-Infrared full-band reduction reflective membrane system 2 consists of ultraviolet-visible-near-infrared band refractive index, but medium and long infrared refractive index, which is composed of alternate stacking. The transparent material of the Zhongyuan infrared band, of which the absorb...

Abstract

The invention discloses an ultraviolet-visible-infrared full-band absorber, comprising: a substrate with a mid- and far-infrared band absorption function; an ultraviolet-visible-infrared full-band anti-reflection film system arranged on one side of the substrate; The UV-Vis-NIR absorption film system on the other side. The invention also discloses a preparation method of an ultraviolet-visible-infrared full-band absorber. The ultraviolet-visible-infrared full-band absorber of the present invention can achieve high-efficiency absorption in the entire ultraviolet, visible and infrared wavelength bands, has a simple structure, low cost, and is suitable for mass production in a large area.

Description

Technical field [0001] The present invention is a field of mixed gown, spatial detection, imaging, light thermal conversion, and electromagnetic absorption, which involves a polar broadband absorber with ultraviolet-visible-infrared band. Background technique [0002] Although the research on the wide wave band absorber has been carried out for many years, most of the research is limited to visible-nearly infrared bands, and rarely involves ultraviolet-visible-infrared full bands. In fact, carbon nanotubes or titanium oxide nano tubes and their derivatives have excellent absorption characteristics in ultraviolet-visible-infrared full wave section. And multi -field applications. Ultraviolet-visible-infrared full-band absorbers have huge demand in the fields of bruises, light thermal conversion, electromagnetic absorption and other fields. Therefore, a simple structure, simple preparation method, excellent mechanical performance, and excellent chemical stability It can be seen that...
