摘　　要：以帝王蝉蝉翼为基底,通过化学镀镍磷的方法,合成了具有纳米点阵结构的镍磷/蝉翼复合材料,并采用扫描电子显微镜、透射电子显微镜、X-射线光电子能谱仪以及紫外可见近红外分光光度计等对样品的微观形貌、成分和光学性能进行了测试。在实验基础上,结合三维有限时域差分方法计算了制备样品的反射谱,研究了蝉翼有序纳米点阵结构对镍磷镀层减反性能的影响。研究结果表明,亚波长的有序纳米点阵结构与入射光相互作用,能使镍磷/蝉翼复合材料的反射率比在无蝉翼纳米点阵结构基体上化学镀镍磷材料的反射率降低70%以上,这一研究结果可为制备镍磷减反结构界面提供设计思路。The Ni-P/cicada wing composites with nano-array structure were prepared by utilizing Pomponia imperatoria wing as the substrates of electroless plating.The microstructures of the samples were characterized by scanning electron microscope （SEM） and transmission electron microscope （TEM）, and the component as well as the optical property was respectively tested by X-ray photoelectron spectrometer （ XPS） and UV-VIS-NIR spectrophotometer.Moreover, in order to investigate the effect of the nano-array structure on the antireflection property of the Ni-P coating, the 3D finite difference time domain （3D-FDTD） method was used to calculate the reflectance spectra of the synthesized composites based on the experimental data.Result showed that the reflectance of Ni-P/cicada wing composites with nano-array structure was 70%lower than that of the one without the surface structure, which was ascribed to the interaction be-tween the nano-array structure and the incident light.This work could provide inspirations for the antireflective Ni-P sur-face structure design.
