Anodic alumina oxide (AAO) templates with multi-branched structure were fabricated in a phosphoric acid.Atomic force microscope (AFM) was utilized to investigate the unstable growth of porous oxide film in initial stage.The morphologies of cross-section of AAO templates at different current density were also studied with FESEM.The results show that the acquired AAO templates are of multi-branched structure with large size.The diameter of pores on outer surface ranges from 150 to 220 nm,and the width of branches from 100-120 nm.This structure can be due to the unstable growth of AAO film in initial stage.
