Attributing to the ordered and uniform porous structure, anodic aluminum oxide (AAO) membranes are widely used as templates in preparation of ordered nanostructure arrays of functional materials for various device applications. In particular, different plasmonic structures have been fabricated based on AAO membranes for sensing and energy-related device applications. Here, we demonstrate the fabrication of hierarchical AAO membranes with unique and controllable patterns, which provide a promising platform for constructing plasmonic structures. By precisely controlling the potential during the anodization process, the sophisticated structure of AAO membranes can be regulated into many distinctive patterns. After replicating the hierarchically structural AAO membranes with polymer and noble metal, hierarchical nanostructures with unique surface plasmon resonance (SPR) properties can be obtained, which can be developed as a dynamic plasmonic device or SERS substrate. The elaborate regulation of hierarchical AAO membranes broadens the scope for the functional nanostructure design, as well as applications in the fields of plasmonic switchers, microfluidic engineering, and nanophotonic devices.
