Unlike other studies that have used nanoparticles, the present study used porous anodic aluminum oxide (AAO) substrates with a high depth–width aspect ratio to provide the large surface area required for depositing nickel nanocrystals using electrochemical procedures. Various AAO packages and electrochemical methods of depositing nickel nanocrystals were adopted as avenues of research. This study adopted commercial AAO substrates with a thickness of 60 μm, pore-to-pore distance of 150–200 nm, and pore size of 150–200 nm (Whatman Co.). A nickel sulfamate bath was adopted as the plating solution for the electrochemical deposition of nickel nanocrystals. Under constant current, nickel nanocrystals were deposited on AAO substrates and were successfully reversed onto glass substrates. The characteristics, structures, and surface patterns of the nickel nanocrystals were then observed and measured using a scanning electron microscope.
