Abstract
In this study, a comprehensive and semi-automated model was proposed for the evaluation of average pore size in nanoporous alumina by combining Scanning Electron Microscopy (SEM), Mercury Intrusion Porosimetry (MIP), and computer vision techniques. A new model for the image processing of SEM was developed to obtain quantitative data that can be used to evaluate the average pore size. The results obtained from the model were compared with the results of MIP, and a good correlation was observed, and it verifies the reliability of the model. To the best of our knowledge, this is the first time when these three techniques were combined for the evaluation of pore size in alumina nanomaterials. The new approach is an accurate, efficient and non-destructive alternative to conventional pore characterization techniques.
