Abstract

To realize the hyperspectral camouflage under the background of vegetation, a polyvinyl alcohol based camouflage coating incorporated with green pigment, calcium alginate fibers, lithium chloride and organic siloxane. The water absorption, reflection spectrum, mechanical property and morphology of the coating were investigated. The results demonstrated that the similarity coefficient and the cosine of spectral angle between the coating and green leaves can reach 0.9612 and 0.9891, respectively, in the range of 200–2400 nm. Meanwhile, the fracture strength of the coating achieves 13.11 MPa. The developed coating possesses remarkable application potential in the field of hyperspectral camouflage to improve the survivability of soldiers and equipment on the battlefields.

一种模拟绿色植被太阳光谱的新型伪装涂层

为实现植被背景下的高光谱伪装，研制了一种由绿色颜料、海藻酸钙纤维、氯化锂和有机硅氧烷组成的聚乙烯醇基伪装涂料。研究了涂层的吸水率、反射光谱、力学性能和形貌。结果表明，在200 ~ 2400 nm范围内，涂层与绿叶的相似系数和光谱角余弦值分别可达0.9612和0.9891。同时，涂层的断裂强度达到13.11 MPa。该涂层在高光谱伪装领域具有显著的应用潜力，可提高士兵和装备在战场上的生存能力。
