Abstract

In order to counter the threat posed by new reconnaissance equipment based on hyperspectral remote sensing detection, it is necessary to develop high-performance camouflage materials that are visually consistent with green vegetation and highly compatible with full-band spectral characteristics, thereby achieving a "same color, same spectrum" effect. Based on the spectral properties of green vegetation in the 400~2 500 nm band, the pseudo-boehmite was used to substitute the traditional material and the hydrothermal synthesis technology was adopted to modify the proposed thin hydrotalcite material with the help of environmentally friendly organic pigment and spectral control. Then, the reflectivity of the material in the visible and near-infrared bands was adjusted precisely through molecular-level interfacial modification and doping process. The prepared functional filler showed excellent performance, its "green peak" was located at 552 nm, and its spectral similarity with green vegetation in the visible-near infrared band was as high as 0.991, which realized a high degree of matching with the spectrum of the green vegetation, and it was verified by experiments that the prepared functional filler possessed better hygroscopic, thermal and spectral stability. The research results lay a foundation for the preparation of hyperspectral stealth coating, which is expected to be one of the new camouflage materials against hyperspectral remote sensing detection, and has a broad application prospect in military camouflage and other fields.
