摘　　要：在磷酸电解液中,利用一次阳极氧化工艺成功的制备了具有结构色的多孔氧化铝薄膜。采用交流电沉积方法在氧化铝薄膜的孔洞中沉积金属Co纳米线,得到了高机械强度且具有高饱和度结构色的复合薄膜。控制氧化时间,可以调控复合薄膜结构色的颜色。采用遮挡法,结合多次电沉积工艺,成功的制备出具有彩色图案的复合薄膜。理论分析了薄膜结构色的变化与其微观结构的关系,结果显示,理论分析和实验结果相吻合。Alumina thin films with structural colors were fabricated by means of electrochemical oxidation in phosphoric electrolyte. Porous anodic alumina films embedded with Co nanowires in the pores, and highly color saturation and mechanical strength were fabricated by an alternative current electrodeposition. The structural col-ors of films can be effectively tuned by adjusting oxidation time. Multicolor patterns were obtained by an organ-ics-assisted process with multiple electrodeposition. The relation between the changing of structural colors and construction of films was discussed theoretically. The theoretical results are consistent with the experimental ba-sis.
