Ramana Reddy, P.R.Udayashankar, N.K.Ajith, K.M.2026-02-052016Advanced Science Letters, 2016, 22, 4, pp. 1034-103719366612https://doi.org/10.1166/asl.2016.6956https://idr.nitk.ac.in/handle/123456789/26023Porous Anodic Alumina (PAA) membranes with highly order array of nanopores were prepared by two-step self-organized anodization process. Structural properties of the prepared PAA membranes such as Pore diameter (D<inf>p</inf>), Interpore distance (D<inf>c</inf>), Porosity (P) and Pore density (n) were studied using Image J and SEM image analysis. X-ray diffraction analysis of the prepared PAA membrane was carried out. The pore arrangement regularity was analyzed for different anodization process durations. The effect of anodization process duration on structural features of PAA membranes was investigated. It was pointed out that interpore distance decrease with increase of anodization process duration. © 2016 American Scientific Publishers.
