Fabrication and Effective Factors Investigation in Nano porous Alumina (AAO) template Synthesis

In this research, Anodic Aluminum Oxide (AAO) template has been fabricated by two-step anodization process in ۰.۳ M oxalic acid. Among the effective factors on the nanopores that formed on the aluminum surface, voltage, electrolyte temperature, anodization time and the type of electrolyte can be mentioned. Also, these factors affect the geometrical features, including porosity, pores diameter, interpores distance and etc. The calculated values for pores diameter and interpores distance are about ۵۴nm and ۹۸nm respectively and the porosity is ۲۷.۲۴% with ۷(μm/h) as the rate of oxide growth, that is considerable in compare to the samples with high purity. In this work, we used SEM analysis and two software WSxM and Measurement for samples analysis
