Ordered arrays of nickel nanotubes (see figure) have been prepared by a novel and universal approach, utilizing the triblock copolymer Pluronic P123 without any surface modification to the porous alumina template. The wall thickness of the nickel nanotubes can be adjusted by the electric current density and electrodeposition time. Magnetic measurements on the array of Ni nanotubes reveal an enhanced coercivity compared to bulk Ni.
