Minimizing Color Difference in AAO-Based Coatings for Urban Camouflage
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...

| description | 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 (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi mathvariant="sans-serif">Δ</mi><msubsup><mi>E</mi><mrow><mi>a</mi><mi>b</mi></mrow><mo>*</mo></msubsup></mrow></semantics></math></inline-formula> < 1.6). The chromium-coated samples had slightly lower matching accuracy (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi mathvariant="sans-serif">Δ</mi><msubsup><mi>E</mi><mrow><mi>a</mi><mi>b</mi></mrow><mo>*</mo></msubsup></mrow></semantics></math></inline-formula> < 3.0), but still displayed rich coloration, with color difference within human-perceptible tolerance limits. |
