摘　　要：用高吸水材料、干叶粉、铬绿为原料,以新鲜植物叶片的反射光谱特征为模拟参照依据,设计了一种类植物光谱特征的填料,并将其加入到聚氨酯基体中制备成涂层。在较宽波长范围内对该涂层的反射光谱进行了研究,并用SEM对涂层的微观形貌进行了表征。实验结果表明,该涂层在400~2500 nm波段与植物叶片的反射光谱特征相一致,其相关系数达到0.9601,实现了对植物叶片反射光谱的高相似度模拟。In this research, the reflectance spectra characteristics of fresh plant leaves were analyzed and a coating simulating these vegetation spectra characteristics was designed and realized in the polyurethane coating filled with super-water-absorbing material, dry leaves, and dichromium trioxide. The reflectance spectra of coating was studied in a quite wide range of wavelength and its microstructure was characterized by SEM. Results show that the coating’s reflectance spectra characteristics are consistent with that of plant leaves in 400-2500 nm wavelength range with the correlation coefficient up to 0.9601, which implies a significant matching for reflectance spectra of plant leaves.
