Abstract

The invention relates to a preparation method of an organic-inorganic composite infrared stealthy material. The preparation method comprises the following steps: firstly preparing alumium-doped zinc oxide by virtue of a sol-gel method, and then covering the alumium-doped zinc oxide with a layer of conductive polymer by virtue of in-situ chemical oxidative polymerization. The excellent infrared stealth property of the alumium-doped zinc oxide is organically combined with unique infrared absorption and reflection properties of the conductive polymer, and consequently, the obtained material is wide in infrared absorption band and good in infrared stealth effect.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a preparation method of an organic-inorganic composite infrared stealth material. Background technique [0002] With the development of science and technology, modern military technology has reached the level that "targets can be destroyed as long as they are discovered". In order to improve the survivability and penetration ability of weapons and equipment, the simplest and most effective means is to adopt stealth technology. Stealth technologies developed according to different detection technologies mainly include: visible light and near-infrared stealth, thermal infrared stealth, radar wave stealth, laser stealth, artificial smoke screen stealth, etc. Infrared detection technology is one of the main means to detect military targets, therefore, the infrared stealth material against it has become one of the most important stealth materials. [0003] The doped oxide se...
