Fabrication of a regular tripod Ni-P nanorod array and an AAO template with regular branched nanopores using a current-controlled branching method

摘要

We present a current-controlled branching method for the fabrication of anodic aluminum oxide (AAO) templates with a triply-branched nanopore structure. By controlling the current density in the branching process, a regular triply-branched nanopore array structure was obtained in the AAO template conveniently and precisely. Based on this template, a regular tripod Ni-P amorphous nanorod array was fabricated by electroless deposition. The present method is particularly advantageous for the fabrication of templates and materials with a complex and accurate multiply branched nanostructure.
