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.

使用电流控制分支方法制造规则三脚架 Ni-P 纳米棒阵列和具有规则分支​​纳米孔的 AAO 模板

我们提出了一种电流控制的分支方法，用于制造具有三重分支纳米孔结构的阳极氧化铝 (AAO) 模板。通过控制分支过程中的电流密度，在AAO模板中方便、准确地获得了规则的三分支纳米孔阵列结构。基于该模板，通过化学沉积制造了规则的三脚架 Ni-P 非晶纳米棒阵列。本方法特别有利于制造具有复杂且精确的多支化纳米结构的模板和材料。
