随着军事隐形、太阳能转换以及激光热处理等技术研究的日益深入,对表面吸收膜的技术要求不断提高。为满足太阳光谱吸收的要求,研制了一种在400~2500nm波段具有强吸收作用、适应多种基底的光学薄膜。通过分析吸收理论,建立吸收结构模型,并结合材料的特性研究,实现了吸收膜的设计。采用真空离子辅助沉积技术,根据逆向反演法,对“分步沉积”工艺二次优化,制备了太阳光谱强吸收膜。测试结果表明,研制的吸收膜在400~2500nm波段的平均吸收率为98.15%。制备的吸收膜通过了机械牢固度测试,与基底能够很好地结合。
With the military invisibility, solar energy conversion and laser heat treatment and other technology research is more and more in-depth, the surface of the absorption film technology requirements continue to increase. In order to meet the requirements of solar spectrum absorption, a kind of optical thin film with strong absorption in 400-2500 nm band was developed to adapt to a variety of substrates. Through the analysis of absorption theory, the absorption structure model is established, and the absorption membrane design is realized by combining with the research of material properties. Using vacuum ion-assisted deposition technique, according to the reverse-inversion method, the “step-by-step deposition” process is optimized for the second time to prepare the strong absorption spectrum of solar spectrum. The test results show that the average absorption rate of the developed absorption film in the wavelength band of 400-2500 nm is 98.15%. The prepared absorbent film passed the mechanical fastness test and combined well with the substrate.
