研究了类叶绿素活性颜料在伪装应用中的光谱性能及光稳定性问题。从绿色植被的色素着手, 分析了叶绿素的性质及影响其降解的原因, 用Cu2+、Zn2+金属离子替代天然叶绿素中的Mg2+, 制备了叶绿素衍生物, 并通过光谱特性和光稳定性对叶绿素衍生物的特性进行了比较分析。研究结果表明, 从光谱性能和稳定性两方面综合考虑, Cu叶绿素更适合作为叶绿素修饰目标来提高颜料的稳定性, 从而为新型光学伪装涂料的制备提供材料基础。

The spectral performances and the photo-stability of the active pigments of chlorophyll are mainly researched. According to the pigment in green plants, the characteristics of chlorophyll and its degradation factors are analyzed, and then chlorophyll derivatives are prepared by replacing Mg2+ in natural chlorophyll with the metal ions of Cu2+ and Zn2+, furthermore their characteristics are analyzed comparatively through the spectral characteristic and photo-stability. Research results show that Cu chlorophyll is more suitable as the target of chlorophyll modifying to improve the stability of the pigments from considering spectral characteristic and photo-stability together. Thus it provides material basis for the preparation of new optical camouflage paint.
