Fabrication of novel nanostructure materials on various metal substrates receives large attensions for numerous industrial applications. In this research, the influence of substrate temperature and electrolyte composition on pore parameters and oxide film thickness of anodic porous alumina (AAO) were studied. A 3D-printed solutionflow type microdroplet cell (SF-MDC) was used for the fabrication of AAO membranes in aluminum substrate. Alumina lines were formed at a constant applied voltage. The temperature of the substrate was controlled with a thermoelectric Peltier device system in the range of 10 degrees C to 60 degrees C. The surface and cross-section morphology of the anodic oxide lines were observed using a scanning electron microscope (SEM). The result showed that the pore diameter and interpore distance of the anodized lines increased as the substrate temperature increased. A highly ordered with hexagonal pore arrangement and lowest film thickness were obtained at the highest substrate temperature of 60 degrees C. The porous AAO membrane film thickness formed in the oxalic acid electrolyte increased from 32.2 mu m to 52.5 mu m as the anodizing substrate temperature reached 30 degrees C and then declined to 12.8 mu m with increasing temperature to 60 degrees C. A through-hole porous AAO membranes were successfully fabricated at constant applied voltage and room temperature in oxalic and phosphoric acid without chemical etching.
