Morphology of fabricated nano-templates plays a significant role in nanoengineering and technology. The geometrical properties of nanopores in synthesized nanomembrane is influenced by various anodizing parameters such as anodizing time, the concentration of acid, voltage applied and temperature of bath solution. The current study exhibits a computerized, automated tool to extract and measure geometrical features of nanoporous media. Nanopore radius and nanopore circularity of Anodic Aluminium Oxide (AAO) are determined in this study by different anodizing parameters. The experimental results illustrate that as the anodization time is increased (5mins, 9mins, 20mins and 30mins) while keeping the constant value in concentration (5%), temperature (200C) and voltage (50 V), the nanopore radius have gradually increased from 7.9nm to 11.6nm and nanopore circularity has decreased from 0.73 to 0.56. Similarly, as the voltage is increased (35V, 40V, 45V), the nanopore radius increased gradually from 8nm to 13.3nm and the nanopore circularity increased initially from 0.68 to 0.78 and decreased to 0.66 by maintaining the concentration (4.7%), time (8min) and temperature (50C) constant. When the concentration (4% and 5%) and temperature (200C and 250C) has been altered keeping time (20 min) and voltage (50 V) constant, the increase in nanopore radius from 55.6nm to 67.4nm and increase in nanopore circularity from 0.55 to 0.67 is observed. The features drawn from values of nanopore radius and circularity are verified by professional chemical experts, which ensure the exhaustiveness of the proposed results.
