Thermal Hardening and Defects in Anodic Aluminum Oxide Obtained in Oxalic Acid: Implications for the Template Synthesis of Low-Dimensional Nanostructures

Indium nanowires with diameters approximately 300 nm have been synthesized by a hydraulic pressure technique using anodic aluminum oxide (AAO) templates. The indium melt is injected into the AAO template and solidified to form nanostructures. The nanowires are dense, continuous and uniformly run through the entire ∼60 μm thickness of the AAO template. X-ray diffraction (XRD) reveals that the nanowires are polycrystalline with a preferred orientation. SEM is performed to characterize the morphology of the nanowires.

Anodic Aluminum

Anodic aluminum oxide (AAO) was prepared in three types of aqueous solutions with various applied voltage. The mechanical property of AAO prepared in different electrolyte was investigated and hardness was increased on account of the increase of the thickness between pores. The mechanical property and microstructure change of AAO prepared in oxalic acid at 40V was investigated by heat treatment. AAO prepared in oxalic acid at 40V was transformed from amorphous to crystalline phase by heat treatment above 800oC and hardness was increased about 2.6 times with increase of heat treatment temperature.

Template synthesis of silver nanowires is studied in this paper. Unlike previous studies, highly ordered polymer-based template fabricated by nanoimprinting lithography was used instead of porous polycarbonate (PC) and anodic aluminum oxide (AAO) templates. This new template combines the advantages of the traditional templates and overcomes their drawbacks at the same time. Electrodeposition was carried out under different overpotential and time periods. Long single silver nanowires were found in the templates. The average length of the nanowires was much shorter than the length of the template, which can be explained by difficulty of plating solution diffusion. Wettability of the template and how to increase channel filling rate were also discussed in this paper.
