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 nickel-phosphorus / onionwing composite with nano-lattice structure was synthesized by electroless nickel-phosphorus plating on the basis of the euonymus cicada wing. The morphology of the composite was characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy and UV-visible near-infrared spectrophotometer and other samples of the micro-morphology, composition and optical properties were tested. Based on the experiments, the reflection spectra of prepared samples were calculated by the finite three-dimensional finite difference time-domain method, and the influence of cicada wing ordered nano-lattice structure on the anti-reflection properties of nickel-phosphorus coating was studied. The results show that the subwavelength ordered nanocrystal lattice structure interacts with the incident light, which makes the reflectivity of the Ni / P fly-wing composite material better than that of the electroless Ni-P material on the base of the moxa-free nanocrystal matrix Reduce more than 70%, the results of this study can provide design ideas for the preparation of Ni-P anti-retrogradation interface.
