Embodiment 1

[0045] In this embodiment, the technical solution of the present invention is described in detail by taking the preparation of plasma and magnetic integrated Ni nanoparticle film as an example.

[0046] The preparation method of the plasma and magnetic integrated Ni nanoparticle film of the present embodiment comprises the following steps:

[0047] (1) Select the forewing of Papilion butterfly as the butterfly wing with anti-reflection microstructure;

[0048] The following pretreatment and activation treatment were performed on the forewings of the selected Papilionidae: first, soak the wings in absolute ethanol for 30 minutes; take out deionized water for cleaning; then soak the wings in 15% HNO3 solution for 2 hours; take out the deionized water and wash it; then soak the butterfly wings in 40% ethylenediamine absolute ethanol solution for 6 hours; then take it out and wash it several times with deionized water. The above steps are used to remove the pigment and impurities...

Abstract

The invention discloses a plasma and magnetism integrated metal nanoparticle film with an antireflection microstructure and a preparation method thereof. The method comprises the following steps: selecting, pre-treating and activating butterfly wings, chemically depositing plasma resonance and magnetism integrated nanoparticles on butterfly wings, carbonizing the butterfly wings in vacuum, and the like. The method for preparing the nanoparticle film is used for preparing the plasma and magnetism integrated metal nanoparticle film by utilizing the butterfly wings, is simple, safe and stable in preparation process, low in cost and low in energy consumption; the prepared nanoparticle film realizes macroscopic large scale, and has the antireflection microstructure of the butterfly wings. The film has high-absorption antireflection performance in the whole solar spectral band, has excellent infrared photothermal conversion performance and thermally-induced magnetic variation effect, so that infrared photo-induced magnetic variation is realized. The plasma and magnetism integrated metal nanoparticle film can be used for preparing an infrared photo-induced magnetic variation film for recording infrared optical information by applying the infrared photo-induced magnetic variation.

Description

technical field [0001] The invention relates to the field of metal nanoparticle films, in particular to a plasma and magnetic integrated metal nanoparticle film with an anti-reflection microstructure and a preparation method. Background technique [0002] The relatively mature nanoparticle film system preparation methods include chemical vapor deposition (CVD), ion sputtering, high-energy ball milling, electroplating deposition and plasma arc and other methods. However, there are some defects in the above methods, such as high energy consumption, low output, poor morphology of prepared products, uneven particle size, difficulty in preparing multi-component coupling nanoparticles, and difficulty in coupling submicron structures. The promotion and application of these preparation methods are limited to a certain extent. Therefore, finding a simple and effective production method is the current research focus and hotspot in this field. [0003] Breakthroughs in functional mat...
