specific Embodiment approach 1

[0026] Specific implementation mode 1: In this implementation mode, a method for preparing a repairable dynamic infrared radiation control material is completed according to the following steps:

[0027] 1. Preparation of SEBS solution:

[0028] Adding SEBS powder into THF, completely dissolving the SEBS powder into THF under the conditions of magnetic stirring and heating to obtain SEBS solution;

[0029] 2. Scratch coating of SEBS film:

[0030] Pour the SEBS solution on a clean glass surface, and then use a manual scraper to scrape and coat it to form a film;

[0031] 3. Peel off the SEBS film:

[0032] Dry the SEBS film scraped on the glass at room temperature, soak it in an ethanol solution after drying, and peel the SEBS film from the glass in the ethanol solution, transfer the SEBS film to the surface of the filter paper, and then dry it in an oven. Obtain an unsupported SEBS film;

[0033] 4. Preparation of gold-plated SEBS film:

[0034] The vacuum thermal evapor...

specific Embodiment approach 2

[0036] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the mass fraction of the SEBS solution described in step 1 is 6% to 12%. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0037] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the speed of the magnetic stirring described in step 1 is 100r / min-1000r / min. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a preparation method and a repairing method for a repairable dynamic infrared radiation regulation and control material, relates to a preparation method and a repairing method for f an infrared radiation regulation and control material and aims to solve the problems of complex excitation mode and poor stability of the existing dynamic infrared radiation regulation and control material. The method comprises the following steps of 1, preparing an SEBS solution; 2, coating an SEBS film by a blade; 3, stripping the SEBS film; 4, preparing a gold-plated SEBS film; and 5, generating cracks on a gold layer of the gold-plated SEBS film in a mechanical stretching manner to obtain the repairable dynamic infrared radiation regulation and control material. The repairing method comprises heat treatment. The repairable dynamic infrared radiation regulation and control material can be reused for multiple times as a new generation of dynamic infrared radiation regulation and control material. By using the preparation method, the repairable dynamic infrared radiation regulation and control material can be obtained.

Description

technical field [0001] The invention relates to a preparation method and repair method of an infrared radiation regulating material. Background technique [0002] Infrared radiation control materials play a pivotal role in the fields of energy-saving buildings, smart wearable thermal management, infrared thermal imaging and stealth, and aerospace thermal control. At present, there are two main infrared radiation control materials, the traditional static control materials and the rising dynamic control materials. The dynamic control materials have attracted much attention because they can control infrared radiation in real time and on demand. Dynamic infrared control materials are mainly electrochromic materials and thermochromic materials, and these materials need to maintain a certain voltage or temperature to stabilize the effect. This is not an ideal control method in terms of energy saving. Therefore, through simple and direct excitation How to realize infrared radiatio...
