用电化学法制备了高度有序的多孔阳极氧化铝模板,选用CoSO4和CuSO4的混合溶液为电解液,用交流电化学沉积法在多孔阳极氧化铝的柱形微孔内制备铜钴合金纳米线有序阵列。分别用扫描电镜(SEM),X射线衍射仪(XRD)对多孔氧化铝模板和纳米线阵列的微观形貌和结构进行分析。结果显示,制备的合金纳米线表面光滑、均匀,纳米线中的晶粒在长过程中有(111)晶面的择优取向。用UV3101分光光度计测试了铜钴合金多孔铝复合结构的透射光谱及偏振光谱表明,合金纳米复合结构在可见及近红外波段具有良好的透射比和消光比;铜钴合金纳米复合结构的确能够改善单一金属的特性,比如在近红外光区,其消光比(30 dB)优于铜纳米复合结构(17 dB)。 A highly ordered porous anodic aluminum oxide template was prepared by electrochemical method. The mixed solution of CoSO4 and CuSO4 was used as the electrolyte, and the Cu-Co alloy nanowires were prepared by AC electrochemical deposition in the cylindrical pores of porous anodic alumina Sequence array. The morphology and structure of porous alumina template and nanowire arrays were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that the surface of the prepared nanowires is smooth and uniform, and the preferred orientation of the (111) crystal plane in the nanowires during the long process. The transmission spectra and polarization spectra of Cu-Co porous aluminum composite structures were measured by UV3101 spectrophotometer. The results show that the alloy nanocomposite has good transmittance and extinction ratio in visible and near-infrared range. The Cu-Co alloy nanocomposite structure can indeed improve Single metal properties such as extinction ratio (30 dB) are better than copper nanocomposite (17 dB) in the near infrared region.
