摘要
应用扩孔和增大阳极氧化电压的方法制备了不同孔径的多孔铝模板,并以交流电沉积法在该模板沉积铜纳米线.测量了铜/多孔铝复合膜的透射光谱和偏振光谱.实验表明,扩孔和增加阳极氧化电压都使样品的透射率下降,但扩孔不能提高它的偏振性能;提高模板氧化电压则可以提高样品的消光比,且消光比随纳米线直径的增加而增加.
Porous alumina templates with different apertures were fabricated by the pore widening and increase of the anodic oxidation voltage, and then Cu nanowires were synthesized in porous alumina templates by alterna- ting electro-deposition method. The transmission spectrum and polarization spectrum of Cu/PAA composite films were measured. Experiment have indicated that both the pore widening and increase the anodic oxidation voltage can make the transmittance drop, but the pore widening cannot enhance the polarization performance of the micropolarizer. The extinction ratio can be improved with increase of the template oxidation voltage or the Cu nanowires＂ diameter.
