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 alternating 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.
