Template free synthesis of beaded aluminium sub-microwires via pulse potential electrodeposition

Abstract

Beaded aluminum wires consisting of rope-like wires with evenly-spaced beading are formed by using a square-wave pulse potential electrodeposition method from a chloroaluminate ionic liquid without the use of a template. The physical dimensions of the beaded aluminum wires such as the diameter and spacing between the nodules can be tuned by changing the pulse potentials and durations, which control the growth mechanism.
