We explored anodic aluminum oxide (AAO) stealth materials combining low infrared emissivity and visible structural coloration through multi-parameter modulation. Using DC ion gold sputtering and UHV magnetron chromium sputtering, we successfully prepared an AAO stealth material with high-saturation visible structural coloration and low infrared emissivity (ε < 0.17). Quantitative evaluation based on the CIE Lab color difference model indicated that the gold-coated samples had high matching accuracy with PANTONE standard colors (ΔEab* < 1.6). The chromium-coated samples had slightly lower matching accuracy (ΔEab* < 3.0), but still displayed rich coloration, with color difference within human-perceptible tolerance limits.
我们通过多参数调制探索了兼具低红外发射率和可见结构色的阳极氧化铝(AAO)隐身材料。利用直流离子镀金溅射和超高真空磁控铬溅射,我们成功制备出了具有高饱和度可见结构色和低红外发射率(ε < 0.17)的AAO隐身材料。基于CIE Lab色差模型的定量评估表明,镀金样品与潘通标准颜色具有较高的匹配精度(ΔEab* < 1.6)。镀铬样品的匹配精度略低(ΔEab* < 3.0),但仍呈现出丰富的色彩,色差在人眼可感知的公差范围内。
