| Abstract: | In this paper, a new way to prepare one-dimensional gradient materials with a graded size was proposed. By varying the anodic conditions, a two-step anodic oxidation of high purity aluminum was improved for fabricating porous alumina templates with a graded pore diameter. Based on the templates, the graded Bi nanowires were achieved by electrochemical deposition. SEM and TEM images show that the resulted Bi nanowires have obvious graded diameters along the nanowire direction with gradient ranging from about 11 to 55 nm. These graded Bi nanowires may be used as a kind of new functional graded materials due to their gradient structure. |
